Never got a chance to work on it last nite, however I am using a single filament bulb(1156) and a 63 in the bottom < am I supposed to be using a dual filament where the 1156 presently sits the top bulb? I will have to check the grounding I guess I am just flustered when I take my tester and place it on the pigtail and see that I am completing the circuit, yet the light when placed in the socket doesn't light up...but you guys are giving some good routes to check...either I have a bad connection at my posts on the light itself or I have a poor ground as my truck was just painted so possibly that is part and parcel of the problem at hand, I hope to get another kick at the cat after school today...thanks for all the tips guys!
