PAGAO USB Rechargeable Bike Rear Light,Super Bright Bicycle Tail Light, Waterproof Bike Light, Suitable for Installation in Helmets, Backpacks,Get It to Kids Men and Women for Safety

this is a very bright light with one major oversight, when it's mounted to your bicycle seatpost it will not pivot in the Y plane, meaning you can't tilt it up / down...it's at whatever angle your seatpost is at which means your brand new shiney blinky light will be facing downward and not horizontal or level to the ground facing the traffic behind you. The light will rotate 360 degrees with the mount provided but since the light is already circulular what's the point? The light gets a 2 stars for me for the brightness - it's very bright - which is good, but if you can't adjust the light to point into the area where you want hazzards to see you then this safety light loses it's effectiveness. Again, very bright, but a major design flaw that it won't adjust up or down when mounted to seatpost. AND NO!, if you flip the mount 180 degrees the hard plastic mounting bracket does not make any difference in terms of angle adjustment.

Small. Lightweight. Powerful. Using it on a Bell Annex helmet. Clip rotates 360 degrees. The light needed a full charge before it would start flashing when switched on (USB cable and silicon mounting strap included). Not sure how long a charge will last. There are several brightness / flashing patterns to choose from. You can't beat the price.

This light is blinding bright! I know drivers will see my bike now from near and far. It can either clip on or strap on the bike, and rotates 360 degrees. I highly recommend this tail light if you want to be seen day or night, and the best part... It's rechargeable.

Very Bright only used once but had the back of my bike lit up!!! I’ll buy again...

Perfect little light!. Don't expect too much brightness at daylight, but at night, nobody will want to be behind you!.

BRIGHT AS HE11 and DEFINATELY serves the intended purpose.
