Topic: Does brake lights come on when exhaust break is working?

Posted By: supercub on 04/15/11 08:21pm

On the Safari I use to have, the manual said the brake lights would come on when the exhuast brake was working.
On the 05 Revolution that I just bought, I haven't found anything in the manuals saying if the brake lights come on with the exhaust brake or not........so my question is......does anyone know if they do on a Revolution. Any yes, I know I could have someone follow me and see......but I hoping to find an answer here quicker. Thanks

Agree on no standardization. I found out my Jake Brake triggers brake lights when I drove it at night and saw the glow in my rear camera.

Of the three MH's I've owned two DID NOT turn on the brake lights when using the exhaust brakes. This MH does. Thanks Mdprince for answering the OP's question.

I work in a fleet shop, no motorhomes of course but pretty much everything else. On all of the vehicles we have using auxiliary braking (Jake or retarder) the brake lights do activate when engaged. This is not however a guarantee as it depends on the manufacturer. All of the chassis have this option, it depends more on the body builder as to wether it's utilized or not. It more or less comes down to how the unit was specced.

There is a Diode that may or may not be plugged in to one of Your electrical Panels. Look for a socket that looks like it should contain a standard automotive fuse. It will be labelled Aux Brake or similar!There should also be a Relay in an adjacent socket!

Gents,
Since I'm very close to purchasing our first D/P, and all I've test drove have had an exhaust brake, I'd assume that if, your applying ANY BRAKE at all, that means your slowing down, which I also would assume the brake lights should come on to warn anyone behind you. If, you were using the exhaust brake and slowing down enough for someone to run into you because you absolutely no indication that you were stopping or slowing, then, what kind of argument would that be in court?

Yes, I know that 99.99999999999% of all rear end accidents are the fault of the following person. But, With the DOT, NHTSA, NTSB and any other government organization that wants to get involved, would mandate brake lights to come on when any brake system is applied.

All of our fire trucks were equipped with primary and "secondary" braking. That is, the primary brakes were the "service brakes" that were applied with your feet on the pedal. The "secondary braking" was either an exhaust brake, in the form of "Jake Brakes" or what's called a "Telma Retarder". Any form of braking applied the brake lights on our trucks.

Regarding the legal issue about the need for brake lights coming on when the exhaust brake is activated, would not the same issue apply to the use of gears to slow down as well?

I remember years ago there were lights being offered that one could put in the rear window. They would show green when the accelerator was being applied (low vacuum), amber when coasting and the accelerator was not being applied (high vacuum), and red when the brakes were applied. Now, that tells all.


Posted By: mdprince on 04/16/11 04:09am

On my Rev, yes the brake lights come on when the exhaust brake is on, and or when the brake pedal is pressed.

Mike and Trish: Excellent comment, made me go out and make sure I wasn't daydreaming.
Msmith1199 had an excellent comment. In his scenario someone's going to get hurt.
Here's what I found. The brake/back-up/turnsignal is about five and one half feet above the concrete. Stay with me now..about 30 inches above the aforementioned light is a one inch wide and 12 inch long "Jake Brake" light on each side.
And on the curve of rear/roof are the DOT lights. Could be wrong, but I touched them with my hand. Now there's more to it but I'm a simple man.

Both answers "mine do and mine don't".

Sounds like you are going to have to find out the hard way and have someone follow you to verify yes they do or no they don't.

On our 08 Vacationer the 3rd brake LED cluster illuminates when the engine brake is activated. The outside brake lights then come on when the brakes are applied. I figure they did it this way since an LED cluster does not generate the heat of a conventional lamp assembly.

My brake lights come on with exhaust brake and here's the problem I have with that. Yes, the exhaust brake does slow you down, but so does taking your foot off the accelerator. When going down a steep grade by exhaust brake may be on all the way down which means my brake lights just stay on all the way down the grade. That's fine if you also don't have to brake while somebody is following you. For example I may be doing a steady 55 coming down the hill with the exhaust brake on and when I come up on a curve (or a slower vehicle) and have to use the real brakes, the people behind me have no warning that I'm going to slow even more.

My thoughts as well.

On our 07 Monaco-built Safari, the brake lights come on when the exhaust brake's in use.

Hmmm ... that would be a new one on me. The three lights at the top are part of your marker lights. As explained to me by the examiner on my Class B license test, vehicles over 7 feet (I think) wide (including dually pickups) have 3 marker lights at the rear top center.

Howdy!

Our brake lights do not work when the exhaust brake is activated. We have even had people pull up alongside us advising us that our brake lights were not working. When we stopped to check they worked fine. We use the exhaust brake most of the time even if not towing on our MDT. It saves on brake ware.

KNparker,
Well Sir, that would most likely be correct for our department too. I was never involved with that part of the details of specking out our rigs. I was involved with "outfitting" them once they arrived and, to somewhat, how the compartments and interior was built from the factory. But, never got into the lighting etc. Thanks for clear answer.

Our city buses in Portland Maine use to have a two color system--red for the service brakes and yellow when the bus was slowing down because of transmission retarder.

On our 03 Dynasty they do NOT come on when the Jake brake is applied. Only when the brakes are depressed. Mike.

Interesting thread. It tells me that there must be no laws governing the brake light coming on when the exhaust or jake brake is applied. I had a problem with my 2000 Freightliner XCS chassis in that my brake light came on when the exhaust switch was on whether the exhaust brake was activated or not (foot off of the accelerator). I found this out one time when I turned on my emergency flashers with the exhaust brake switch on. There was no flashing just a continuous on.
At a Freightliner rally I used their free tech service, and two techs spent half a day going over my my MH and wiring diagram to finally find a cut wire. They fixed it and now the brake lights come on with the exhaust brake only when the brakes active not just when the switch is on. They took my request very seriously because they probably considered my problem to be a safety issue. Wiring problems are a bear and I am glad I didn't have to pay for their work. It would have been at least $1000. They sure won some more loyalty from me.

On our rig only the center brake light comes on when the engine brake is working.

garry1p: You are on the money. I followed my DW and Towed down to Tucson. Works as I explained, except RV and towed brake lights do not come on until the RV brake pedal is depressed. I touched my driverway, it's concrete, what? yours is gravel.

Relish the "mine is bigger" that is going on.

We have had 3 motorhomes; a Monaco, an American Coach, and a Fleetwood coach. On all three motorhomes, the brake lights come on when the exhaust brake is applied.

We currently have an '05 Revolution LE, and its brakelights do come on when the exhaust brake is applied.
