psi check

designer's own words:
PSI Check is a pressure monitoring valve stem cap that allows the viewer to instantly see if their tires are properly maintaining air pressure. The top of the valve cap accurately displays the tire’s current air pressure. Arrayed around the valve cap are five L.E.D warning lights that illuminate to notify the driver that a tire is 10% under
inflated and in need of air.
