Ok first let me say I am way out of my element on this question, but that won't stop me from giving you a comment.
My thinking is , what gets activated at "5 MPH", and my thought is the cruise control. Does the cruise control work OK? Reason I ask is the cruise control won't come on unless you are going over some set MPH, right? Maybe when that MPH is reached the cruise control is activated and so are the lights. When some cruise controls "see" the brake lights is deactivates, I'm just thinking maybe there is a problem there.
Love to hear the answer to your question by someone really knowledgeable.

The cruise should NOT work if the brake lights are ON!

Do you have ABS? Doesn't a ABS system have wheel speed sensor on each wheel?
Maybe something wrong with the ABS ECU?

This is a good comment and is kind of true, depending on where the manufacture selects to get the input for the cruise control. What I mean is, the cruise is set so when you press on the brake pedal, cruise control goes off, but that might not be at the same point where the lights are activated. The lights could come on first then the cruise disconnect, or the other way around. Something is activating the brake lights in the Jeff's unit, but he indicates the cruise control is still working.
In my Saturday or shade tree mechanical mind, I'd first look at the brake light switch. Its cheap and maybe would be easy to replace. Who knows, maybe it just adjusted so close to coming on it does when the unit is being driven somehow.

If Jeff's unit has ABS then your statement is true, but now you are talking $. I always look at the cheap things first!!!  Good comment though, and this still may be the culprit. Cars/trucks are getting more and more complicated and interconnected all the time.
As I said, I'm only a shade tree mechanic, and the smarter cars/trucks get, the dumber I feel. Old age could also play into this also.
Good luck Jeff!

Regardless of equipment, if you're on cruise and you tap the brake, CC is gone.
Really looking forward to where this ends up.

Have some further thoughts:
1) Air in the brake system. Bleed the brakes.
2) Return spring on the brake pedal not strong enough.
3) Brake light switch slightly mis-adjusted and as you pick up speed the pedal sinks a bit causing the brake lights to turn on.

Just my thoughts on this topic. As someone earlier stated, your cruise should disengage if your brake is applied and I believe you stated that it was still working, therefore either there is a problem with your cruise as well but my guess is that it is not your brake light but possibly your clearance light that is turning on.
Having said all that, the question is why above 5mph, back to CC again?

Could your pac or exhaust brake be turning the light on?

Maybe your bell crank is not disengaging the brake pedal plus if need to be adjusted can remove two wires off brake switch and thread plunger in or out to adjust.

brake light help from workhorse chasi
I must say this was my first post and thanks to all for the replies. Actually a email to workhorse resulted in two phone calls!!! The workhorse east coast regional service director did reaserch on my unit and found the brake pump was replace with a generation two brake control panel, the system will not work correctly with the motorhome so they have located a module generation one tow replace it with. I was very impressed work horse replied in this manor. I will update if this gets done and all is followed tru with Thanks> Jeff Baskin

Sounds like you dropped a "Wooozer?!" question in their lap. Wonder how many other units there are out there with a similar issue?
