Looking to replace my euro trash headlight with a bullet headlight, but the only one available seems to be a CEV sealed beam headlight. I was wondering how they hold up or if I should continue my search for the non sealed headlight. Do you have to replace them often, since the voltage varies with mopeds? Moped Division seems to sell the bulbs for $10 vs. the cheaper 1156/7. Can anyone tell me if Tomos runs on 6V or 12V?
