FAQ

Q1: Will these affect my TPMS system?
A: Absolutely not. Each weighs only ~2 g and integrates seamlessly with tire monitoring systems.

Q2: What's the duration of the glow?
A: Once fully charged by light, they emit for 4–6 hours before gradually dimming. Recharge by exposing to light again.

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

Q4: Does sunlight fade the color?
A: No. UV-resistant ABS material preserves vibrant colors through extended outdoor exposure.
