i dislike them very much. Wouldn't put one on my bike and think they should be outlawed on motorcycles. Every time I see one of these coming up behind me regardless whether I'm on the bike or in the cage, I want to pull off the side of the road thinking it's an emergency vehicle especially in the daylight when the compliment of red/blue lights aren't seen.
Yeah, my high beam plus the Kury driving lights get enough attention for me. That said, if I'm right behind somebody for a while I turn off the driving lights--pretty bright in the rear view.
