Rechargeable Bike Light, Color Changing LED Disco Headlight Headlamp Taillight Flashlight Cycling Bicycle Accessories by WopWorths

The battery doesn't last 3 hours, as far as I can tell. I've gone on rides of less than three hours and the light is already off b/c the battery is drained. It actually would not be a problem b/c I have power banks that I could just use to charge up the battery while it is working. I'm not sure if the battery charges while it is working, or only when it is off. Mind you when the light is working it's great: It's bright it has lights that alternate colors and a motor that spins it all around - the effect is awesome. I get compliments here and compliments there. But it doesn't have a big enough battery that can power it for long enough, and I can't tell if you have to plugged into a power bank if it will keep on operating - I've gotten mixed results. Put a bigger battery in it.

Super cool because I can use the for when we go bike riding but I was also able to use the lights outdoors! Happy with the purchase. I’ll post and update a picture of what it looks like in my backyard when I get a chance we just finished putting more trees up and it looks really cool outside!

Looks great. The mount is cheap and not intuitive at all, but it works.
