Frequently Asked Questions
How long does the glow last? ▼
It’s 100% passive! After 10–15 minutes of exposure to sunlight or bright light, they will glow brilliantly for hours. They recharge automatically every time you drive during the day.
Will they fit my specific car/bike? ▼
Yes! We use a standard 8mm inner diameter (Schrader valve), which fits 99% of cars, SUVs, trucks, motorcycles, and bicycles.
Are they safe for high-speed driving? ▼
Absolutely. The built-in Precision Rubber O-Ring ensures a tighter seal than stock plastic caps, preventing air leaks even at highway speeds.
Are they waterproof for car washes? ▼
Yes. The high-density ABS material is 100% waterproof and corrosion-resistant. Rain, mud, and high-pressure washes won't affect the performance.
Why aren't they glowing out of the box? ▼
They've been in a dark shipping box! Just place them under a lamp or sunlight for 15 minutes to "wake up" the luminous crystals before installation.
