Mine look like Friar John's posting. Work great. 55 watts each. I leave them on all the time. Cost: $15 at Walmart. As I remember, they were made by Optimus or Optiplex or something like that. You need the round ones (not ovals) to fit. They mount through the existing holes in the lower fork triple tree as shown. I have used them for several years. Cars notice me, but don't flash their high beams at me. Best of all worlds.
