Stand out and be seen 24-7 with Sunset Skateboards' signature LED wheels. Four ultra-bright LEDs illuminate the wheel's crystal clear PU bringing your Sunset skateboard to life day or night. These wheels offer the brightest LEDs in the industry and have the capacity to glow for a staggering 100,000 hours. Batteries... NO! The LED wheels self power off the spinning motion of the wheel therefore no batteries are ever required. Each Sunset Conical Cruiser wheel is cast in high quality clear 78a Poly-Eurathane (PU) for that super smooth cruiser ride you are used to. Each wheel is embossed with our original Sunset logo.
