Bont Glow LED Wheels are hybrid indoor/outdoor roller skate wheels that use LED lights embedded in the core to illuminate the tires. A magnetic floating spacer powers the lights; all you have to do is roll and your wheels light up bright with a luminous neon glow. Glow Wheels have a hardness of 83A, which allows them to skate comfortably on sidewalks or in skating rinks just the same! The LED lights also serve as a safety feature when skating outdoors in poor light, illuminating your skates and announcing your position.
