The Seba Luminous wheels are very beautiful wheels that give a very beautiful light in the evening.
The reason why these luminous wheels are so beautiful, are the LEDs inside the wheel, that light up in an alternate way instead of all together.
Contrary to the light-emitting wheels of other brands, e.g. the red wheels are always red, also when not rolling, and when rolling they light up with a red color. (And the same is valid of course for all the other colors.)
And indeed, black is a somewhat special color for a LED wheel!
