There have been a number of threads about tail lights, the consensus of which led me to buy a diNotte tail light a year ago. This week, with days growing shorter, I pulled the little blinkie off my commuter and brought out "the big guns;" my dual diNotte headlights and my diNotte tail-light.
In three days of commuting this week, I have had the following occur:
1. Driver at stop light: "Wow, what a tail light! I could see you forever."
2. Biker at stop light: "What kind of tail light is that? I need to get one."
3. Biker passing me on suburban road: "Wow, what a tail light."
4. Pedestrian at downtown stop light. "Wow, that's some light."
BTW, I had the light on "low" since it isn't really that dark yet during my commute....
I got these kinds of comments all last winter...I had just forgotten how frequently people comment on the light since I hadn't used it most of the summer. I actually point the tail light down so it doesn't blind anyone; and I always ask bikers who comment on the light whether it was 'too bright.' The headlights are bright, too -- on MUPs I always point them down and/or cover them with my hand when I'm approaching another biker.
Just in case you are still wondering what kind of tail light to buy....
