Have a 2003 Holiday Rambler Endeavor. Both headlights will come on for 2 seconds then go out....then blink on & off randomly, every 2 sec to 10 sec. Fuse is in good shape. Owner's manual and Electrical Distribution Panel do not reference a relay for the headlights, so I'm assuming there isn't one. Headlight switch on dashboard is a plunger style. I've wiggled it around (while pulled back) & it doesn't affect the lights blinking on & off. Nor does the high beam lever on steering column affect the blinking. Any advice as to what could be the issue?

Do all lights blink or only the head lights?

Only the headlights...and randomly...no predictable pattern.

Headlights are normally on a circuit breaker. My first guess is a filament issue in one of them. Shorted filament could cause tripping of the circuit breaker.

Check the alternator voltage.

It could be a loose wire or socket or ground connection, too, besides the things already suggested.

On a lot of cars the CB is in the hlight switch.

Had a car that did the same thing. Circuit breaker was in the switch. Switch would get hot and lights would go out for a few seconds and then come back on. This scenario kept repeating. Replacing the switch solved the problem.

I had a car that did this and it turned out to be the headlight switch.

Daylight Running Light Module (Hamsar?) will also do that when it fails.
