Make your skateboard or cruiser stand out day and night with these awesome light-up wheels! The Slime Balls Chrome Light Ups are 66mm in diameter and made from a soft 78a urethane, which gives a smooth, comfortable ride over rough pavement. The coolest part? The built-in LEDs light up as you roll, powered by a special spacer system—no batteries needed. They come with removable Bronson G2 bearings installed, so you can pop them right onto your trucks. The transparent neon blue color looks rad, and the neon graphics add extra flair. Just make sure to use the included spacers and tighten your axle nuts fully for the lights to work. Perfect for cruising, commuting, or just having fun. Light up the streets!
