I have a 77 Puch and the headlight is pretty dim, to a level where I can barley see 5 feet ahead at night. Currently there’s a 6 volt 21 watt bulb that I recently installed but I wanted to know how I could convert my setup into a 12v system. Do I absolutely need one of the treats 12v coils to run it? Also, if anyone has converted to LED, I’m interested to hear how that was done.
