My headlights started flashing on/off when on the way home tonight. What would I look for to diagnose?
Link to headlight relay upgrade:http://www.trifive.com/forums/showthread.php?t=57359I had the same problem with mine. It happens after a few minutes after turning the headlights on. It's your circuit breaker that's built into your switch. It weakens with age, and it's there to protect the circuit from cooking. Easy fix, is to instal a headlight relay. Works well, with no problem and takes the power load off your switch. Another positive to is you can run brighter lights.
X 2 on this as being the likely culprit.Overload or short in the headlight wiring circuit....Or possibly a weak breaker on the headlight switch.....See link:http://chevy.oldcarmanualproject.com/shop/1955/55csm1204.html
