Query: Bright and convenient

I'm very satisfied with this light. The benefits are:-- Since I always have my helmet, now I always have a light, even if I forget my other lights.-- It's pretty bright; I can see the reflection off traffic signs several blocks away.-- The reflector design makes it pretty visible from a wide angle, more so than my bike headlamp.-- The on/off switch "remembers" which of the four modes you were last using (full on, blinking, center LEDs, or side LEDs).-- Anything that gets more attention is good!Things that could be improved are:-- Some way to adjust the angle. Right now I shove some rubber under the bottom of the light to get it up to the angle I want.-- A separate mount for the helmet strap and head strap. Right now to use it as a head lamp, I would have to completely remove the mount from my helment.
