Review on 🚲 CUGBO Pack of 30 LED Flash Tyre Wheel Valve Cap Light for Car Bike Bicycle Motorcycle Wheel Light Tire (Red, Yellow, Blue, Green, Mixed) - Enhance Your Vehicle's Visibility and Style with Colorful LED Wheel Lights by Trae Joubert

Good idea! I thought they would be fun. They came in packs of 2 and there was no way to tell what color they were other than turning them on. I took out all the discarded plastic from the battery area. When I did, I noticed that not many of them turn on. I figured I would just put them on the bike, unrolled them and then put them on. I drove around the block and only one worked so I replaced them with others. In total I was only able to get 6 of them to work. Not much for her. They look like a flashlight so it's not hard to see how they work. I only wish they were!
