Packet of 2 Blue Bike Wheel Rim Lights by EstiLee-Extra Bright LED Bicycle Tire SpokeLit Valve Cap Flash-Waterproof & Shockproof-Plastic-for Motorcycle Car-Best for Safety and Warning Signals

Mixed feeling about these...they light up nicely, but also in an unpredictable manner. I have them on my son's bike and one will start blinking if you just touch the bike. One of these let the air out of the tire when I screwed it on, the other was fine. I needed to unscrew one and then duct tape it to a spoke so it won't deflate the tire.

These are so cool and help keep you safe at night on a 49cc scooter, they are long so I had to bend them to one side but love how they turn off when you'er not moving.

Unfortunately, I would not reccomend these. One of these lights does not work for me. The material is cheap and prone to bending, so you cannot screw these onto the valve of your tire in any kind of secure way without bending the electronics.

Didnt work,.. Wasted my money on these.

Although I loved them initially, after I changed the batteries, one stopped working. The construction is cheap and unfortunately it doesn't last.

Wishing the description included that these would not fit with presta valves. I found out once I received them and scrolled through the questions to problem solve how to put the lights on.

Really like these. As your bike wheels turn these lights blink on and off continuously and quickly. Excellent safety device.

These work as advertised. They are on during the daytime but are bright enough to be seen. When the motion stops, the lights go out.Initially one of the two did not work. Since it wasn't worth sending it back, I tinkered with it and got it to work.
