2003 Ultra Classic---Upgrading stock sealed beam passing lights to halogen 55 watt lamps with replaceable bulb. Stock sealed beam has two connection points. One gray/black stripe wire and one black wire which is riveted to passing lamp case. Upgraded lamps come with one white wire which I assume is the hot wire. Does the ground for halogen use the case lamp and ring for ground for lamp? If not how do I wire this? This was purchased from JPCycles and is a nice looking upgrade....This site is great for us want to be mechanics with questions.....THANKS YOU, MAC
