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 Mondreka Rosenhoover

Pretty difficult to photograph them in motion. But they work. My wife wanted them for her bike and we rode them last night and coming to their site I can confirm they work as described. I don't know how they stand up to the humidity. As with the first activation, you must remove the battery cover to remove the protective strip for the batteries to complete the circuit. They don't have a ring for the battery cover or where it screws onto the valve stem. I rate it 5 stars because everything works as advertised.
