Gumdaat Universal Fluorescent Car Tire Valve Caps Cover Accessories Glowing in Dark

1, DOUBLE PROTECTION: The fluorescent car tire valve caps feature illuminated plastic inserts and clear housing protection to prevent valve stem corrosion. Our tire valve caps inside with the Rubber Seals, create a tighter, more effective seal, so there's no air leaking on long, tough drives.

2, FLUORESCENT EFFECT: The inner layer of the valve stem cover is designed with luminous material, which can make the car decorated with Tire Valve Stem Caps lights at night. When your wheel starts to move, it automatically flashes and creates a circle of light that makes your car/motorcycle/bike look beautiful.

3, WIDELY USED: The inner diameter of tire valve caps is 8mm, which fits most cars, buses, SUVs, trucks, motorcycles, bicycles, etc., keeping the tires of vehicles at the proper inflating level.

4, NOTE: Since the fluorescent material needs to absorb the light source, it glows at night. Stem caps do not absorb light sources when stored in airtight packaging for extended periods of time. Illuminate with LEDs or place them in sunlight for 4-6 hours before using fluorescent stem caps for the first time.
