Luminous Led Glowing Wheel 76mm

The Luminous glowing wheels are LED wheels with phosphorescence.
This means that they also glow in the dark when the wheels are not turning (and so you will stay visible).
The pictures alternately show the wheel in daylight and in the dark. In this case the reality is rather difficult to capture in photos. (To get the right diameter you should look at the title and not at the pictures.)
The spinning Luminous wheels are very nice because the LEDs in the wheel light up in an alternating way instead of all together.

(The official name of the orange wheel is "Luminous 76 Sunray Glow".)

(If you inline skates have 6mm axles, you need for every wheel an aluminium spacer adapter .)
