Ok here is the picture, a 1960 GMC with dual headlights. 1st what are the normal headlights that work on low beam? Outside set or the inside Set. "I" think the outside set are low beam.
At normal night time driving the low beam seems fine, when I hit the highbeam switch the truck headlights change angle and get brighter, but the same two lights are what is switching. (I swear I'm not making this up). The inside pair never come on. I did not notice this until last night when I pulled up to the garage and switched the high beam off.
I wonder how the PO has this wired or are is it simply the wrong bulbs on the truck?
