CycleBeam(TM) TAILDUO-50 Aluminum Bike Tail Light

Really bright lights but the size of seat post was not posted. So it was a little to big for my seat post. So a rubber shim was needed. Other than that extremely bright and visible.

Works really well. My only complaint is that they don't include shims. Other than that very satisfied.

This is great light. It's made from aluminum and not plastic. I've had other lights that would come flying out of their brackets every time I hit a bump. These lock securely in place and aren't going anywhere. The two lights turn on individually and have two modes, flashing or steady. The only complaint I have is that the clamp is a little big for my seat post. I had rubber shims from other accessories that I used to mount it but it would have been nice if the light came with them.An unexpected bonus is that the light came with batteries installed plus 4 more sets of batteries (each light takes 2 batteries).

The tail lights fit my husbands' bike perfectly, and give out the appropriate amount of light so he can be seen at dusk or dark. They also came with extra batteries, which we hadn't expected, but is a plus! We also received it very quickly! A five star experience for us!

This dual light is very cool, most rear lights are single staged, this dual is bright and flashes so you can be seen from very far away. Diffently a great light, and easy to change batteries. Worth a few bucks, buy it you won't be disappoint
