Liked:
Dinotte 140L Amber & Red (keeps me safe, nice and bright)
PDW Radbot 1000 (good backup light)
SRAM Rival Group (lightweight, crisp shifting, Double tap, most comfortable hoods makes me a new SRAM fan)

Tried:
Bike Brightz Yellow (mediocre brightness, ghetto mounting system)
Lightweights 3M reflector stickers (pain in the butt to install on spokes, not too impressed with reflective properties. Thinking of getting a monkey electric spoke light to increase my side visibility)
