Hey everyone. Did a search already and not finding an answer. Have a strange issue. All lights work fine but the headlights vary in brightness. No other lights including fogs, interior, nor rears seem to change at all. What's the right troubleshooting routine? I do not have a voltmeter gauge in the car.

Are you saying the headlights actively fluctuate in brightness, in tandem? Like a candle flickering? How fast is the fluctuation? Is it better/worse with the car running vs just on battery power?
Can you provide a little more detail of the behavior? You will eventually need a volt-ohm meter (VOM), so now may be a good time to buy one if you don’t already own one. All the above steps are still valid, in my opinion. You’re looking for the reason why enough power is not coming through clean. Could be resistance in the circuit (power and/or ground), or power supply (battery, alternator, voltage regulator). Another thing to try: Make sure the battery connections are clean and try the headlights with jumper cables attached to another vehicle, or to a known good battery, with car running and not. |
