Review on Smart Bike Light Set By BrightRoad - Bright Front 80 & Back 40 Lumens LED Lights, Waterproof Headlight & Tail Light With Auto On/Off Sensor And Built-In Reflectors by Landon Bandepalli

I grabbed this to put on my road bike and have been very happy. Battery life seems exceptional and it seems to charge up fairly quickly. I initially clipped it onto my saddle bag, but it came off a couple times when I hit bumps, so I switched to the provided strap and haven't had a problem yet. The strap has a bit of an angle to it so that when you attach it to your seatpost the light is level, which is nice. And it is BRIGHT! Don't look at it when you turn it on or you'll be seeing spots for a couple minutes afterwards. There are also a few different flash options in addition to an always on setting. Very pleased with it.
