Glow-in-the-Dark Fluorescent Valve Caps

Vibrant Mix – Five Fluorescent Shades

This pack includes colorful valve stem caps in green, blue, yellow, red, and pink. Add personality to all four tires, your bike, and keep a few extras on hand.

Nighttime Glow for Standout Wheels

These caps absorb sunlight or headlights during the day, then glow with a bright neon ring at night—turning heads on every ride. Charge in strong light for 15 minutes before use for best effect.

Sealed with Leak-Resistant O-Ring

A built-in nitrile rubber gasket and precision threading block air loss and moisture, helping prevent tire leaks and extend TPMS sensor life.

Install in Seconds, No Tools Needed

Just twist onto any Schrader valve stem (≈0.3 in ID). Compatible with cars, trucks, motorcycles, BMX, and all types of bikes—road or mountain.

Durable ABS Shell Built to Last

Made of impact-resistant ABS that holds up to UV rays, extreme temps, mud, and car wash cycles—no cracks, no fade.

FAQ

Q1: Do these interfere with TPMS sensors?
A: Not at all. Each cap weighs just ~2 g and works perfectly with tire pressure systems.

Q2: How long does the glow effect last?
A: After a full light charge, they glow for 4–6 hours and gradually fade. Re-expose to light to recharge.

Q3: Will these work on Presta valves?
A: They are made for Schrader valves. A separate adapter is needed for Presta.

Q4: Will sunlight cause the color to fade?
A: No. The UV-resistant ABS keeps colors bold and bright, even after years of outdoor use.
