Why just replace the bulb ? I got tired of loosing bulbs in my Tomos (not easy to replace locally). While I was at the autozone, I turned around and looked at the auto auxiliary lights. I took two of these, mounted them together, and isolated the housing (ground negative is bad on my ped). They look cool, are brighter than the original, and change color from different angles.
