Excuse my ignorance, but has anyone had a headlight switch go bad? My dome lights under the dash ('68 convertible) very often will come on all by themselves. The reason I think it might be the headlight switch is a couple times this happened I turned it back and forth and the dome lights turned off again. But since then when the lights "decide" to turn on they don't turn off regardless of what I try. I can play with the door switches and nothing happens. It seems to me it really can only be the headlight switch.
