Tired of your rear lights working when they feel like it? Go to Radio Shack and buy one package Cat.# 64-3010, and one package Cat.# 64-3017 (small machine screws and nuts). Remove your light boards and put one screw through each of the hollow rivets holding the light sockets. Tighten these down with a vengence. This improves electrical contact immensly. Fixed mine, try it. Thanks to the Pacific Northwest Delorean Club! Additional: If your boards are dirty, clean them first. Radio Shack also sells an oxide cleaner that seems to work.
