I found a short at a headlight connection once ( back of the left bulb ) that powered all at the same time. Dimmer switch seemed inop as the bulbs were higher beam regardless. They did work though. Has anyone considered blown out bulbs here?
Considering all my turn signal indicators and fenders light up with the headlight switch...no...i hadnt considered bad headlight bulbs. I do agree with some kind of short, or backfeed.
Was thinking the headlight switch was my best starting point.
