The previous owner of my bike put on miniature "carbon fiber look" turn signals. One of them has a burnt out bulb which needs replacing. They seem to be made of unobtanium. It's a mini-bayonet base, and has 12V 28W on it (but no bulb number). The glass part of the bulb is elongated compared to all the mini-bayonet bulbs in the (auto) parts store. I can't find any such bulbs online.
For now, I replaced it with the brightest mini-bayonet base bulb I could find, but it's dimmer than the other side.
Does anyone live in a metropolitan area where a shop sells these signals? Do they carry the spare bulbs? Will you please post their contact info?
