4 Pack LED Flash Tire Wheel Valve Cap Light, Colorful | For Bike Bicycle Motorbicycle, 4.25 inch Long

They don't work. Like they work, it not consistently so it looks like you are sputtering. For the price, you pay what you get.

First time out, I lost one of the lights. It fell apart as my tires rotated fast. The other one flew off a short time later. I reinforced the third and forth with epoxy and it seems to be working better. The batteries don’t last long. They seem to dim after the first time out and degrades very fast each time I ride. Lasts around 5 rides. Not much use out of them.

These look good, but all plastic and don't work once applied to the wheel. Works fine laying on the table or while holding in your hand, once put to the tire.... nothing. Do not waste your time.

One was broken in packaging and one broke off while riding the bike so not really strong enough for what it's made for

These are very pretty. but I got them for my car and defiantly not good for a car. There way to big and stick out a lot! but, they would be very cool for a kids bike. its still worth the money for what they are just not meant for a car.

Terrible product they pretty much all didn't work and the one that did work well out of the 4 popped off and broke in 6 days 😅.. Wouldn't allow me to give it 1 star but its not even worth 2

Its ok. Not the greatest batteries. Does stay on for a while after car not moving.

These come with adapters for presta valves, but the soft plastic threads stripped out the first time I tried to screw them on. The lights no longer stay on the valves. Probably work fine on schrader valves but definitely don't recommend for presta.
