Headlights on my 95 Ram 2500 randomly flash off and on when on bright. This usually occurs after driving with brights on for 20 minutes or longer, and most often when pulling a trailer. However, disconnecting the trailer makes no difference once the problem starts. Dim lights work correctly.
Was wondering if anyone could point me to a good starting point for troubleshooting, such as dimmer switch, headlight switch, circuit breaker, etc.?
