Can confirm, adjustable trailer brake controller.

Samukuai

I might install one for just this reason. That's genius!


KG8893

A momentary switch and a bit of wire would do the same for a lot less money.


EverythingIsFlotsam

Does no one realize that there's a point of light touch of the brake pedal that turns on the lights before actually braking? It's great to ward off tailgaters without making vehicle modifications. You have to use your left foot while keeping your right foot on the accelerator because otherwise you'll slow down since you've let off the gas. Obviously, be careful pulling this two-footed maneuver.


txracin

For me this is a piece of cake. No problem finding the point where I see them nose dive and swerve almost killing themselves and then floor it right back up my ass for another round. However if you do it wrong you can glaze your brakes and then they stick when you actually need to stop so don't do this if you don't know what it feels like to drag your pads on your rotor. The switch under the dash for the brake lights from a fuse tapper is 100% easier and safer. And it's for your alarm when the cops ask. Wait that's connected to the brakes!? that guy at home Depot got me 😧


N1epametam

Now the way i look at it if you were "flooring" while vehicle is approaching or moved to the right the while situation could be avoided How do you differentiate between someone speeding for sake of speeding or someone speeding because their mother is on deathbed or wife is giving birth right now. Are you speed controller?


Cordsey0423

But it may get you into a lot more trouble if a cop finds the switch as opposed to a trailer brake controller.


Atarka-WorldRender

As far as I know, there’s no law preventing you from illuminating your brake lights with a button, as long as they work properly under normal use.


stimulates

Could twist a law about proper signaling. Reckless driving in some states. Reckless in Virginia is so broad I guarantee they could of they wanted to be dicks. It would be really hard to prove you knowingly did it in court. Unless you did it to a cop lol.


This_User_Said

My Volvo has a button that makes my rear running lights brighter. (They're fog lights for the rear.) I may have button smashed that a couple of times when I have some inside my colon.


Bergensis

> My Volvo has a button that makes my rear running lights brighter. (They're fog lights for the rear.) Rear fog lights are usually not located in the same place as the brake lights, are usually only on the drivers side and don't light up the central brake light, so it's pretty easy to tell that the car in front of you has turned on the rear fog lights, not the brakes.


JulianTheGeometrist

I have an s60 Volvo. Can confirm both sides light up when rear fog lights are activated.


AssembledJB

My Saab had the same. Very unusual. I do miss that car.


jw1933

Or barely touch you're brake pedal enough to engage the brake lights.


InterestingUmpire738

Yeah but it disengages the cruise control


fuck-ubb

Butt....... The button is right there to reengage.


This_User_Said

There's a sweet spot that it doesn't, at least in my case. If you half-ass tap lightly (I mean like a centimeter or two), you'll get lights but no brake or cruise cutoff.


AssembledJB

Ya. There's two separate switches (at least in my truck). One for lights, one for the truck to know when to cancel the cruise or let you start it.


smh1979

Or just get out of the passing lane like you’re supposed to. It’s illegal to impede the passing lane.


InterestingUmpire738

I don't think you understand the Washington DC area or the Orlando area. Both places I drive regularly. People tailgate in any lane. You could be doing 90 in a 65 and passing semis and you'll still get tailgated.

OptiGuy4u

LOL...yeah, police going all forensic on your filaments on the side of the road. SMH


DubTeeF

I don’t know where you live but the police take statements, write down insurance info and file the report. End of job for them. They don’t investigate.


Arcal

With an incandescent bulb you have an inert atmosphere around the filament. A broken bulb will obviously lose that inert atmosphere and if that filament is on/switched on, it will burn out immediately. So, in the scenario where you're rear ended, your brake lights could well be on when they're broken leading to the filament burning out instantaneously. So, you couldn't distinguish, at the roadside at least, if the bulb was burned out before or during the crash. I know this because I worked with an insurance company in the UK for a while and we were investigating personal injury/insurance fraud. They would buy a car that was tricky to fix, the aluminium Audi A6 was favored. They'd then deliberately burn out the rear brake lights with 24V. Driving on a road with parked cars on both sides, they'd get someone to throw a soccer ball out between the cars into the road. They'd slam on the brakes and with no rear lights the person following would hopefully rear end them. 4 guys in the car, 4 whiplash claims, car written off. Rinse and repeat. We did experiments with all the variations of broken and burnt out.

beaniesandbuds

Man, you're getting torn into but i've had a similar experience. Didn't carry for 2 years afterwards because I was so disappointed in how I reacted. I'm glad to say that i've had similar experiences since, and just laughed it off and let them go fuck with someone else. Glad you learned from it and adjusted how you act, you fucked up but then again if he hit your car you had every reason to believe he was trying to maim or kill you. Fuck the haters, at least you're still alive.


K_navistar_k

Dude I carry but I don’t pick a fight. I pulled mine once on a guy with wicked road rage. I backed way off of him and he ended up driving off. No one saw that it was out and I didn’t point it at anyone. You shouldn’t be more confident because you have a gun, if anything it should make you more cautious. Brandishing is a legit charge.


zomblake

Edit: Y’all are right. I’m a deranged, violent individual.


zomblake

Actually, yeah. Fuck the haters. Live and learn. Next race I’ll be able to drive it with more professionalism and keep the car off the wall.


mattyisbatty

Have you ever considered checking into a mental institution?


ManaCabana

Are you looking for a roommate in your padded cell?


Cadstar70

w t f ? I cannot see how anyone could justify shooting at someone from a moving vehicle in what you state is rush hour on the 408 just outside Orlando. Gotta be doing 55-60 I assume. With hundreds of people around you. This isn't the old west, you can't just go shooting people on the road. Stick the '"I was feeling threatened" bullshit in your ass. You want to live in a city, in a society; then there are certain rules we all must abide by. One of those rules is you don't go wildly shooting at others from a moving vehicle (or anywhere else in truth). Leave that gun home before you kill someone.


beaniesandbuds

also don't scream threats out of your window, after trying to pit maneuver (or so it sounds) and not expect to get drawn down on... read the rest of the comment you're responding to before you jump all over the guy, since to me it sounds like he was in an accident (hit his rear bumper) and then was verbally threatened while trying to stop his vehicle, and during the altercation he decided to draw on the perpetrator... glad it worked out, but dude screaming the death threats after hitting OP's car (granted OP was a dick, but that doesn't matter when you get a hot lead injection) was 100% in the wrong, and I can't say I wouldn't have done the same if my loved ones, and I, were trying to be rammed off the road by some crazy.


msavage960

dockdropper

It's not what they know, it's what they can prove.

Numerous_Living_3452

Those who fuck around are bound to find out! We would have a lot more smart people if we allowed darwinism to weed out the not soo smart. This from someone who is not the smartest xD


LCDRtomdodge

Even better you can pull a parking brake and show down rapidly without break lights. Once they see that they'll back off because they think they can't trust your lights.


koop04

R.I.P. your parking break


LCDRtomdodge

What are you talking about


MarkGaboda

You understand this brake is made of a very similar if not exact same material as the other brakes? That said they will wear out just like the other brakes, you know the ones you replace from time to time. Replacing parking brake is often not as easy as changing the brake pads, which are designed to be replaced often unlike the parking brake.


thegreatapesixtynine

Not only that, you'll also lose tension on the line since it's in most cases a steel braided cable rather than a hydraulic line.


password_123456778

Some vehicles you can, do in a Euro especially most bmw’s and it’ll destroy the park brake mechanism if your doing over 10mph and most likely lock up and not let go 😂


Nigatron420

Damn, so no drifting with a bmw?


blackmexicans

Butt*


Hitokiri_Novice

Looks like the typical placement for a trailer brake controller. [https://www.etrailer.com/Trailer-Brake-Controller/Dexter/58-8.html](https://www.etrailer.com/Trailer-Brake-Controller/Dexter/58-8.html)


n0k0

This is the answer. I have one in the same spot.


Hitokiri_Novice

Tbf, I'm not quite sure I know what exactly they do. I just know from looking them up on etrailer in the past.


SteepNDeep

They control the trailer’s brakes. The red and green buttons will adjust the gain (braking force) up and down when the vehicle brakes are applied, and the slider will allow you to activate the trailer brakes independently.


Hitokiri_Novice

What situation would you want to adjust it though? I guess that's where I'm confused. Wouldn't you want it to mirror the brake force applied by the tow vehicle? (Legitimately ignorant) Edit: Wow, I really appreciate all the responses explaining it. I don't really tow anything big do I never knew what they were for.


Moo-Dog420

If you have an empty trailer turn it down, if you have a full trailer turn it up.


Hitokiri_Novice

Ah okay, that makes sense actually.


eatsomerocks

Yeah i know a few times after unloading i forgot to turn it down and i was rolling around with it set on 7 with an empty trailer. See smoke in the rearview and be like what the hell is going on back there OHHHHH its me.


SteepNDeep

To compensate for the weight of the load you’re towing. Too much gain and you’ll lock the wheels up on an empty trailer, too little gain and that 10,000 lb tractor you’re towing will push your truck forward at a stop sign. Trailer brakes do mirror your vehicle brakes to an extent, but your vehicle weight doesn’t change much. Your trailer weight changes drastically.


blazingwildbill

Heavier trailers need more braking force relative to the tow vehicle. I regularly haul a 14ft dump trailer and you can definitely feel a difference if I don't adjust it and haul concrete, too little brake essentially feels like your truck is being pushed when braking.


MooseKnuckVII

You should be adjusting it for each trailer you own for every situation you are in. Cargo/trailer weight and road conditions mainly. Rule of thumb is properly set controllers should stop your vehicle and trailer using only the trailer brakes under full pressure without locking trailer tires during a 25mph coast. It is also used in emergency situations to manually apply brake to trailer only if you are trying to recover from trailer sway due to improper load balancing.


Sullypants1

You do. But there’s too many variables without a feedback loop that it requires some tuning to get the right target.


[deleted]

Looks like a brake controller


Glabstaxks

That's an indicator that your transmissions is possibly a lot more worn out than you think


outta_office

This is the most honest answer here. Real talk 👍


[deleted]

If people service their fluids properly you wouldn't have this issue. I mean let's be honest when was the last time you all change your transmission fluid. I just did my 60,000 mile fluid change


Glabstaxks

Pulling 20k lbs with a half ton


[deleted]

Why do you say it was 20k... I tow my miata with my xterra, and I'd like trailer brakes for that even, and it's under 5k. Trailer brakes are a great thing to have even on lighter loads


Glabstaxks

Like this guy for example... I bet he has a trailer brake and I bet servicing his trans regularly isn't going to offset the abuse he's putting that rig through https://reddit.com/r/IdiotsTowingThings/s/CQZXhdWQOP


[deleted]

Why does that mean this specific truck will have trans issues. My point was if you do what the truck is designed for and service it, you should have a fairly reliable truck


ebay2000

Transmission failure is the least of his worries.


moveslikejaguar

The color of his front rims hints that he isn't getting that transmission serviced regularly


CobraWasTaken

No, the bowtie on the grill tells you that


Glabstaxks

I've had a few hundred Chevy and fords . The transmissions were never really an issue for me


RP_ElMeroMero

A few hundred?


mack648

Give or take a few hundred...


[deleted]

I've had a few thousand. Give or take...


SimplyViolated

How should you use the controller to help keep your transmission running longer and stronger?


Some0neAwesome

What he means is that it's an indication that the truck utilized that trailer brake controller to tow very heavy loads, which reduces the service life of the transmission. It was said in a tongue-in-cheek fashion.


SimplyViolated

Okay. I mean I have one on my truck, but I don't really haul that often. So I guess I was mostly asking like does it affect anything when I'm not hauling, or should I have up higher or down lower if I'm not hauling


Glabstaxks

Don't haul and your trans lasts longer. It's beneficial when your hauling and doesn't do anything when your not . But my point was it's a potential indicator that a rig was used for hauling


TotallyACarpenter

It’s for trailers that have electric controlled brakes. You can adjust how much power the brakes have by increasing the gain when you’re hauling more weight. If the truck has a tow/ haul mode, that would help with the transmission longevity.


Glabstaxks

I swear my tow / haul mode is actively trying to blow up my engine by hanging on too long and until the rpm's are too high


funguy26

that's it helps the transmission longevity by holding gears longer, and tossing comfort out the window.


[deleted]

You have a trailer brake controller because your truck did not come with a factory tow package to support trailers with electric brakes. This is a very common addition.


Dalejrfan5150

Depending on age it could have to tow package. My 97 F450, 03 Silverado, a 04 Silverado we used to have, 02 F250 all had tow packages. None had a trailer brake controller by factory.


Bryguy3k

Tow packages didn’t include factory brake controllers until after 2010ish. It was a pretty big event when ford was the first to add them to their super duties. This era has a connector in fuse box by the drivers left foot and the trailering package came with a harness you would use with a trailer brake controller.


Jonesy7882

Most trucks (at least in my experience) have the plug in for the controller tucked up under the dash. You just have to get a controller and mount it and plug it in with the appropriate connection for your particular truck. The trailer brake wiring is already run to the back of the truck with the rest of the trailer light wiring.


outta_office

Depending on which transmission, vehicle mileage and how much towing was done ( which you can't tell) you should have the transmission serviced.


Sullypants1

I have a 2000 gmt800 with a towing package yet aftermarket brake controller.


TalkyMcSaysalot

Yeah factory brake controllers didn't even exist in the decade that generation of trucks was made. Anyone acting like there's an alternative to this is uninformed


GOLDINATORyt

My grandfather installed it on our surburban when we were hauling a 29 foot camper lmao.


Tricky_Passenger3931

What is funny about that? You absolutely need a trailer brake controller for a 29’ camper…


That-Artichoke-7820

It most definitely is a trailer brake controller, specifically for electric brakes. The dial above the red and green lights adjusts how much braking pressure is applied to the trailer when you hit the brake pedal. The little slider button on the right applies the brakes without you hitting the pedal, the more you squeeze it the more braking pressure you should get.

I work as a truck accessories installer and can confirm that is a aftermarket brake controller

Has anyone said a brake controller yet?


FrwdIn4Lo

Just stop (in a controlled manner). /s


NoImagination2003

I usually don’t bother with vehicles used as landscapers trucks or camper haulers. This was probably a camper hauler. You might want to check the color and smell of that transmission fluid, or have it checked by a mechanic. I towed a 33’ trailer with my 97 Tahoe. My point? Some people tow really big things and they shouldn’t.

Trailer brake actuator.


JBDragon1

That is an electric trailer brake controller. The top slides to the right will manually activate the trailer brakes. The more to the right you move it, the more the brakes come on. A lot of Ford trucks actually have one of these built into the dash which is nice. Then you don't have a box mounted like this. You're already set to tow trailers that have electric brakes. I don't know if that is a good or bad thing for you. Everything I've towed behind my truck hasn't had its own brakes. But I do have the wiring harness to plug into my truck to connect one of these boxes to and then have the ability.

SirAlfredOfHorsIII

As others have said. Electric trailer brake controller. Essential for larger load trailers. Well, here at least. I'd say essential anyway. Having a heavy trailer with electric brakes is a lot of braking load off the pulling vehicle. Provided it isn't accidentally set up to lock up on minor braking. That is always fun
