Like Brian said, the shift motor what you can do is take it out and coat the while inside after you get the stiff factory grease out coat it with ALL TEMP WHITE LITHIUM, this will reduce the drag on the shifting and make it run much smoother, As for your lights, I'd check you rectifier is it putting out low 13's to mid 14's? Oh forgot when you get all your electrical connections ready to go on, put dielectric grease on everyone of them.
