Glow-in-the-Dark Tire Valve Caps – 20-Pack Neon Green
Battery-Free Glow with Just Sunlight
Crafted from UV-reactive silicone, each cap charges under sunlight or bright indoor light in just 5–15 minutes—then shines with a vivid neon green glow as you ride. Adds nighttime visibility and a cool custom look.
Built-In Seal Keeps Dust and Leaks Out
Each cap features an internal NBR O-ring that prevents water, dust, and debris from entering—helping protect valve stems and reduce slow leaks over time.
Universal Fit for All Vehicles
Fits any Schrader valve stem—just twist on by hand. Great for cars, motorcycles, bicycles, scooters, and trucks. No tools required.
Simple 4-Step Installation
- Remove your existing plastic or metal valve cap.
- Place new cap under direct light for initial charge.
- Screw it onto the valve stem until snug.
- Go for a ride—your wheels will glow as they roll!
