Set of four Luminous Light Up Quad Wheels in Sunray Glow 62mm 85a, fine for both indoor or outdoor use. These are the best light up roller skate wheels we have ever got our hands on, the LED's are super bright and give a smooth even glow.

The lights in the wheels are powered by a dynamo that sits in between your bearings, as your wheels rotate the LED'S activate so there is no need for batteries.
