OP - HIDs are way brighter, and that is good, but:
- your headlights are not designed for them, they will "splatter" (emit light at angles they should not, pissing off driver in front of you and those that pass by you), not a problem for high beams, but is for low beams.
- When I bought my bike a year ago, it had a HID kit already installed. There were issues of the low beams failing to come on at times, turn the key off and back on and it would come on. I replaced everything with another (I thought better) HID kit. All was good for about 5 months, but following a friend home one night, he mentioned the splatter. I enjoyed that it annoyed him (what are friends for
), but didn't like doing that to strangers. I was going to revert to standard on just the low beam (the HID high beam is great for seeing deer), but turning the bike on for work one morning one of the ballasts started smoking. I pulled the HID kit, replaced all wiring with OEM, and have not had an issue since.
I do miss the HID high beam, but don't trust the cheap kits anymore.
I am a sample size of one, so this is somewhat meaningless. I not saying don't go HID, I'm just saying you might want to research the pros and cons a little before jumping in.
