Abstract
A tire pressure indicator is disclosed including a housing having an inlet for air under pressure, a sealed chamber, the chamber containing a gas under pressure, a signaling device having an electrical power source arranged to generate an electrical signal indicative of a pressure difference between the inlet and the chamber, a flexible diaphragm separating the inlet and the chamber, the diaphragm positioned to extend into the chamber as pressure at the inlet increases, a connector operatively engaging the diaphragm and the signaling device to actuate the signaling device to generate the electrical signal, and a light source coupled to the signaling device to receive the electrical signal and generate a visual signal indicative of a pressure difference between the inlet and the chamber.
