LEDs are the way to go. I monkeyed around with the lights for almost a year, swapped to LEDs from Custom Dynamics, no issues. The tail lights are so bright, a fellow BDR guy flagged me down and tried to tell me I was driving with my foot on the brake. Now I have four tail lights and four brake lights, and two turn signals on each side. LOVE it.

An easy way to check if it is a ground wire issue....get a multimeter and check continuity from the socket ground to frame ground.
