I have a set of the reproduction tail lights on my 49 gmc. Each tail light has two single filament bulbs inside. I am using bulbs that say 12v on the package, however, I can't seem to keep bulbs alive in one of the tail lights in particular. I check em, and they are indeed burned out when I change em. What the heck is up?
That is what I am starting to think here. I also got a headlight from the same flaps that was not glue together squarely. It would not fit in the headlight retainer ring. Being out in the boonies, I gently nipped off a fraction of glass off the outer rim to make it fit. If I had been in town it would have gone back to the store forthwith.
