Reinstalled my alpine alarm system for power door lock option. I did not check the headlights after install,parking lamps work on arm and disarm system,washed car and engine compartment, a few hours later,started car turned on headlights no headlights low or high beam??? parking lamps,side mark, etc..all work.. cant find a fuse or circut breaker for headlights... ANY ideas?????

 

There is a self-resetting circuit breaker in the headlight switch. Check the voltage between the red wire and ground, and the yellow wire and ground.

If the red wire is hot and the yellow is not (with the headlight switch on) the ciruit breaker is open. Standard trouble shooting from there.
