Review on WheelBrightz LED Bike Wheel Lights by Brightz - Pack of 2 Wheel Lights for Bicycle Decoration - Top 2021 Stocking Stuffer Present for Kids, Teens, Boys, Girls, Men, Women by Christian Byrd

They were quite bright and I felt they helped a lot with visibility. I originally bought two thinking I would use them on both wheels, but ended up just installing them on the front wheel. However, there are two issues that made me give this one a 3 star rating. 1) Sophisticated Switch: The push button switch didn't seem overly reliable; I pressed it repeatedly and found that it turned on and off with a single press. In the end it stays on (or off). 2) Durability: 14 months have passed since the installation, and now after daily cycling and maybe 200 times use, the light has stopped working. At first I thought it was a dead battery issue, but that doesn't seem to be the case. It's a bit of a shame. I think I might try taking it apart and finding out why it broke. But I'll probably put another one on first (because I still have it) and buy something else in the future.
