I give this a 4 star because you have to buy another adapter to make them work. When you get them to work they are really pretty and colorful. Makes a bike noticeable when riding on a road.

Speed Racer only lights up once put in motion, and thus will not require constant turning on and off. Based on LED technology (light emitting diode), the rim light will endure through almost any terrain as well as rough handling. Want to bike in the rain or through small ponds? The rim lights are 100% waterproof and rust resistant – to put it differently, once the LED has been installed you will never have the hassle of taking it off or putting it on again unless you want to.
As the speed racer is attached and functioning properly, it may enhance safety by increasing visibility at night.
