So my passenger side was flickering last week. I did the grease and ziptie (ziptie only worked on the trucklite-to-trucklite harness plug). I did that to both lights but now my driver side is acting up. It looks like it is the jeep to trucklite harness (green plug). I move the wires around at the base of the plug and the lights turns on and off. I am not sure what to do at this point.
Checked mine last night finally, and forgot the only connection I have is the jeep to the lights since I cut apart the harness and soldered it all together. Seemed to stop after I unplugged it once tho which was strange. I did use the dialectric grease in the jeep plugs tho just incase and it seems okay now.
You may want to take a small flathead screwdriver and make sure all of the terminations are seated in the plug correctly and are making adequate contact at the connection.
