What It Is / How It Works

These are luminous valve stem caps, small decorative covers that screw onto the valve stem of a car, motorcycle, or bicycle wheel. This set of 20 is molded from ABS plastic and comes in five colors: yellow, green, blue, red, and pink.

Who It's For / Use Cases

Valve stem caps suit drivers and riders who want a decorative detail on car, motorcycle, or bicycle wheels. Shoppers who like a glow at night may enjoy the luminous effect, which depends on daytime or other light to charge before use.

How to Use / Care

1. Screw each cap directly onto the valve stem, since the caps are designed for easy installation.
2. After receiving the product, place it in sunlight so the caps can absorb light and begin to glow.

How to Choose

Start with color, since the set offers yellow, green, blue, red, and pink options to match your wheels or ride style. Next, check the size of about 1.6cm by 1.2cm with a 0.8cm inner diameter against your valve stem before buying. Set count is 20 pieces, which suits a full set for several wheels.
