Brake light ground issue

About twice a summer, I have a ground issue with my brake lights. I have to remove the tail lights on my 71 Scamp, twist the bulb socket in the housing and reinstall the light. This freshens up the metal and creates a good ground again and everything works great for awhile.

I bought 2 of the little wire kits to replace the contacts and wires coming out of the housing, spliced them in and grounded the housing and it seemed to permanently cure it.

A nice little rainy and beer afternoon working on the tail lights. :D
