Ok, I have a new 40' straight deck trailer with LED lights all around. I can plug them in and turn my lights on and they stay lit for maybe 10-20 minutes then they shut off, then maybe I wait an hour and I can turn them back on for the same period of time. When they shut off and I try to turn them back on right away they just flicker then go out again. They will still light up when braking, and turning though. What do I need to look for, and maybe change? Thanks!!! Kinda important cause I haul a lot with it, haven't had to really do anything at night yet anyway.

 

Which lights? Clearance lights?

Circuit breaker on your truck is kicking out.

 

Haulin's got it....if it were a ground or connection problem, the time interval (IE: cooling down) wouldn't effect - they would either work or not, and then you wiggle a wire, and they come right on, etc. For an interval, it indicates the circuit breaker has tripped and then is cooling, and then will function, and then re-trip. That would be the first place to look. Otherwise, it must be something in the running light circuit, which is different than brake/turn.

 

LED lights shouldn't draw as much current as regular bulbs, so it seems a bit unusual for a circuit breaker to trip, but it sure sounds like that is what is happening. You might have a partial short in the tail/clearance light circuit on the trailer causing a high current draw.

I would stick an amp meter between the truck and trailer to see how much current draw you have and go from there.

 

Ok, thanks guys. I'll check that stuff out and keep you posted on that! Thanks again.
