Glow-in-the-Dark Fluorescent Valve Caps

Five Vivid Neon Tones – Vibrant Selection

The collection features eye-catching valve stem caps in pink, yellow, green, red, and blue. Personalize your vehicle's four wheels, your motorcycle, and stock up on spares for later.

Luminous Shine at Night for Standout Wheels

During daylight or when struck by headlight beams, these caps soak up light energy, then radiate a vibrant neon circle once darkness falls—creating an eye-catching display wherever you go. Let them sit in bright light for 15 minutes initially to maximize performance.

Secure Gasket with Air-Tight Seal

Featuring a nitrile rubber seal inside and fine-threaded design to combat air escape and water infiltration, they reduce the risk of tire damage and help protect TPMS sensor functionality.

Quick Install Without Equipment Needed

Simply screw onto any standard Schrader valve stem (roughly 0.3 in ID). Fits cars, SUVs, ATVs, BMX bikes, and every cycling style—whether commuter or off-road.

Tough ABS Construction for Long-Term Use

Built from sturdy ABS plastic that resists impacts, sunlight degradation, temperature swings, dirt, and automated wash systems—maintaining color and shape over time.

FAQ

Q1: Will these caps affect my TPMS sensors?
A: No concerns here. At approximately 2 g each, they function seamlessly alongside tire monitoring technology.

Q2: How long does the luminescence persist?
A: Once fully charged by light, the effect lasts 4–6 hours before gradually dimming. Return to bright light to restore the glow.

Q3: Are these compatible with Presta valves?
A: These are designed for Schrader valves. You'll need a separate adapter if you have Presta.

Q4: Does sunlight fade the color?
A: No. UV-resistant ABS material maintains vibrant color, even with prolonged outdoor exposure.
