Review on Stay Safe And Visible Anytime With GPMTER Ultra Bright USB Rechargeable Bike Tail Light - Perfect For Road And Mountain Bikes by Mark Bullock

For starters, they're bright. While I ended up receiving two red lights instead of one of each color, I just put the other red light on my helmet.The mounting of the light is straight forward, and because of the rubber strap, you can secure the light on many different areas of the bike. Mounting the light on my helmet was just as easy. I have my tail light next to the wheel hub, so it's out of the way of my panniers.Only negative so far is that the clip between the strap and light itself is near impossible to undo. If I want to take my light off so I can charge it, I have to take off the actual strap because the light can't clip off.EDIT: No problems yet, I've owned it for a few days now, and have found that it's just the helmet light that won't un-clip from the mount. The light I use on my bike, however, clips off with ease.
