You can pick up 48 volt dc to 12 volt dc converters that are small and cheap. I like running 12 volt bulbs better just because they are easier to find if one goes bad.
Title says almost everything. I'd like to find a few old-bike reasons to get out of Lubbock in the next few months. Preferably west of I-35. Kansas, Oklahoma, and New Mexico would be fine too.
Thanks!
