I bypassed the LCM , Thanks justbob, and installed a low amp trigger electronic flasher. I have replaced the bulbs with LED's - front park/turns, and the four tail stop bulbs. I used Sylvania Zevo for the rear. I thought all was good until I found that with the car in run and the headlight switch off the inner tail bulbs light dimly, the outers are more dim but flicker. With key off everything works just fine i.e. the tails do not light except in proper circumstances. I did all my testing that way. The front parking lights behave properly.

Somebody asked me why I had flashing taillights driving down the road.

Any history of this happening and solutions?
