I want a HL/TL for the purpose of being seen by others, not so much to see at night.
When the sune starts going down, it goes from bad to worse, people backing out in front of me, etc. I rarely (okay, never) ride in the dark.
I'd like something easily moveable from one bike to another
If not rechargeable, AA Batteries
Under $100 for the combo. Cheaper is better
