Last night, on my '96 Ram 2500 12-valve, turned on the headlights, had no dash lights. Jockeyed the switch around a little, dash lights came on, headlights went out. I haven't noticed any hot smell as though the switch is overheating (doesn't mean it isn't, though). Truck is not equipped with any extra lights other than 6 LED-type running board lights. Checked previous posts regarding headlight switch and it sounds as though I need to get the Summit harness. I don't think it comes with the headlight switch. Anybody know of a good outlet other than the Dodge dealer (over $120 for a headlight switch there).
