Issue with LED brake light remains on

Sounds like the problem is that your trailer has a high-mount brake light that was wired into the electric brake circuit instead of a lamp circuit. Obviously trailers have no provision for a brake lamp wire in the 7 pin connector so this lamp was wired into the brake circuit. The Prodigy monitors that circuit with a small voltage pulse, which seems to be enough to illuminate the high mount lamp. The easiest solution would be to simply disconnect the lamp. You can't hook it into one of the signal lights because it will flash with the turn signal on that side.

I believe this is an excellent description of the blinking 3rd brake light.

I am puzzled why Robbies Grandpa and me are the only ones to seem to have this problem. Actually, I think it's more widespread with Prodigy owners than they realize.

Also, I'm puzzled why the Prodigy person I spoke with replied he had never heard of this problem, and blamed it on my trailer wiring.

Finally, I did what Robbies Grandpa did and wired it to a tail-light wire so it comes on with the lights, and is not functional as a brake-light. Jack
