so i have and issues with my headlights they worked fine when i got my truck and then the lights started flickering a little and fluctuating when i would throttle at idle telling me it might be alternator or battery but the battery is new it looks like and the alternator has been giving me problems i.e. losing or snapping my belts i finally got fed up and started looking myself under the connections and found the dimmer switch was burnt up i replaced it and it seemed to work well and then i went to drive home and they started flickering and then id mess with all the connections and couldnt find any pattern in the way the lights would flicker and also when the truck is off the lights dont flicker which also makes me think its alternator
My car has a manual transmission.
