I sold my SoCalMoto HID's and am currently running bright halogens. Overall, I still think HID's are a good solution but certainly not perfect. My main issue with the HID's was light scatter and a resulting loss in clean cutoff. My plan was to convert to LED's but so far have not found what I like. Eventually, that will be the way to go and, in fact, I'm confident future Goldwings will come with LED headlights.
Thats what I am using not silverstar ultras.
