I also wear a neon vest now, reflective stickers on helmet and do a lot more lanesplitting than I used to. I'll pull up next to the cars at lights and have enough speed/pickup to get in front.
I used to hate doing that, but one of my accidents was getting rear-ended by a drunk in a cadillac while behind another car at a light. Had whiplash problems ever since.
I like the idea of a light on the helmet. I'd like to figure out how to get discs brakes on my Urbans. (edited)
