I went and bought a set of H7 Superstar Ultra bulbs for my '04 RC today, but they don't fit. The prongs are shorter, and closer together so they don't fit the sockets. Did I miss something? Are the Ultras different from normal Silverstar H7's? Am I trying to use the wrong type of bulb? I was pretty sure reading here that H7 is the correct bulb. Let me know what you think before I return them, thanks.
