Just brought my bike home - WOW!!! Those 55W HIDs are bright!!!
Ummm, at least I think they are. It's somewhat subjective since I cannot compare them side-by-side with the 35W lights. I did look into the lights - which I'm pretty sure I also did with my 35s and these were almost like looking into the sun.
I forgot to ask if everything needed was in the box - but I assume so since they didn't have to waste time ordering anything and my service report didn't indicate any parts for HIDs. They mounted the ballasts on the steering head which worked well before.
The price difference between 35W and 55W at DDM Tuning is negligible ($25?). In my mind it's one of the best safety related mods you can do.
I don't know if I'd consider replacing a set of 35s w/ the 55s; but for a first time install or (for me) replacing broken parts: it's an easy upgrade decision.
