Charge-free glow activates under light, delivering neon green visibility to your wheels. This 20-pack uses UV-reactive silicone that charges in just 5–15 minutes under sunlight or bright indoor light, then emits a vivid neon green glow as you ride. They enhance nighttime visibility and give your ride a distinctive look on any bike, scooter, car, or truck.
Universal fit for Schrader valve stems—simply twist on by hand, no tools required. Suitable for cars, motorcycles, bicycles, scooters, and trucks.
Each cap incorporates an internal O-ring made from NBR to seal out water, dust, and debris, helping protect valve stems and reduce slow leaks over time.
Install in seconds: remove your existing valve cap, expose the new cap to direct light for a quick charge, then screw it onto the valve stem until snug by hand. Go for a ride—the wheels will glow as you roll.
