I love this Victagen USB Rechargeable Bike Safety Led Light it is great at night. It is super bright and you can see at a far distance. This is also great to keep as an extra flashlight for emergencies. It comes with a hook you can put on your bike with a rechargeable battery that can be charged up multiple times which is something I really like about this.
This light changes throughout pushes of the button meaning there are different light options one is just a bright steady light, the next is a strobe light, it also comes with a small red light that is supposed to be used for a tail light this one does not have a rechargeable battery this also comes with a USB cord to charge the battery. The battery is 3200 MAH 18650 battery.
It also comes with the instruction manual on how to mount these to your bike which is really nice so you are not guessing. On how to work it. This light will light up 219 to 328 yards which is a pretty far distance. When you mount this light it has a notch that you slide it into you and make sure it locks into place.
