Southwind 32V Grade Brake

[supercub]

On an 07 Southwind 32V with the grade brake, does the brake lights activate when the grade brake is working? The reason I ask is, I have a SMI stay n ply tow car brake system. It works by sensing deceleration and the brakes lights being activated. This was a problem in my DP using the exhaust brake, becuase the brake lights came on....hence the tow vehicle brakes would be applied for a long period of time while descending grade. If the brakes lights on the Southwind don't come on with the grade brake, I won't have a problem. Thanks

If the grade brake is the same as was available in the GM pick-ups, with Allison trans , it is a transmission, gear down program only , no brake lights involved unless your using them.
No info in the W/H owners manual ?

Had a thought on how to confirm this for your self, if you have your 4 way flashers on, and touch the brake, if the flashers stop, the brake lights have over ridden the flashers ( my F/L does this), then try the same with the Grade Brake, if the flashers stay on then there is no brake light function in the Grade brake.

With my 2005 you turn off the overdrive to do that function and the brake lights do not come on
