I had issues as well with one not firing, then the other. Sometimes neither would. Pulled both grounds and re-did them. Bought two self-tapping stainless steel screws from hardware store. Sanded some paint off the corner of the frame above the headlight housings and drilled those suckers in. Tightened the hell out of them and covered them with flat back spray paint. NEVER had an issue since. :woot:For those of you with the headlight firing issue, try adding an inline fuse. Fixed my issue.
