Yep, the Jacobs Exhaust brake on our coaches does turn on the brake lights on the coach. HOWEVER, if you have cruise control engaged and the exhaust brake kicks in on a gradual downslope, the brake lights DO NOT come on.
If you get a toad brake that is triggered by the brake lights on the coach, yes, it will be triggered when the exhaust brake comes on. But you can get a toad brake that works differently. There are many out there.
I have the Roadmaster Brakemaster toad brake system. It ties into the coach air brakes, and brakes the toad proportionately when I press the brake pedal in the coach. It comes with a breakaway system and monitor light on the coach dash that is tied into the brake system on the toad so is illuminated only when the toad brakes are actually applied. My toad left & right brake lights do come on with the exhaust brake if the cruise control is not on. Then when I press the brake pedal hard enough to trigger the toad brake pedal, it lights up the third brake light on the toad. M&G and many other toad brake systems work similarly, not being triggered by the brake lights but only by pushing the coach brake pedal.
I do want the brake lights to come on when the exhaust brake is engaged as I use it for stopping, downshifting the transmission to 2nd, normally hit the coach brake pedal only at the very end of a stop (or when I have to make a quicker stop.)
