Abstract: A tire inflation indicator is integrated into the sidewall of a tire to give a visual indication of proper pressurization. A small lamp is imbedded in the sidewall and is electrically connected through the sidewall to a pneumo-mechanical switch and battery. The switch connects the battery to the lamp when the tire pressure falls below a predetermined level.
