HELP w/ dome lights

This is a fastback Barracuda? Are you refering to the side courtesy lights? Did you remove the rear door panels and metal surrounding the side courtesy lights looking for the wiring? Im sure its there as I do not understand why anyone would remove it??....When you mention the covers, do you mean the light lenses? The bulbs for these are hard to find, but there is a substitute bulb you can use that is more modern and brighter. I will have to dig the bulb number up for you but they are available at all auto parts stores, a little shorter in length but still "clips" into the factory wiring holddowns on these cars....
