How it works
Take off your valve cap and screw a StemFlare on by hand. Four lights cover every wheel on a car.
A motion sensor switches the light on as the wheel turns and off again when you stop.
A threaded metal cap with a bright PVC light tube. Batteries come installed, ready to go.

The ring effect
As the wheel spins, a single glowing stem traces a complete circle. Parked, it's a clean metal cap. Rolling, it's the wheel everyone looks at.
