Can anyone direct me to a link or describe how this mod is done? I did about 10 minutes of googling to no avail. I'm sure I could figure something out on my own, but why re-invent the wheel? See the pic if you don't know what I'm referring too. 56 Buicks stock have a tail light lens at the top of the housing, and a chrome piece with a back up light on the bottom. The pic is of dual lens' top and bottom.
