Valve Cap, 2-pack
Self-illuminating valve cap with a green or yellow LED for Schrader and Dunlop valves. The light is activated by the wheel's rotation and creates a circle of light that is easily visible in the dark. The light turns off as soon as the wheel stops spinning. Replaces the original plastic valve cap.
Powered by the three supplied silver-oxide batteries (SR 54, 1.5 V). NOTE! Remove any protective paper around the batteries.
