I have a 1975 250 Enduro with lights and Motoplat Ignition. The bike is currently not running as I am restoring it. I'd like to run a Preston Petty front number plate headlight and the original round tail-brake light. My original Penton Manual says the ignition is a 35 watt output. Should I be running 6 or 12 volt bulbs ? Thanks for any insight.
