ABSTRACT:
A tire pressure indicator has a spring-operated sensor mounted in an air chamber of a housing that attaches to a tire pressure valve. Indicator has adjustment screws, accessible from the exterior of the housing, for setting the sensor to a low level of acceptable tire pressure and a high level of acceptable tire pressure. When the pressure level outside of the set limits is detected, a bicolor light emitting diode provides a warning to a driver.
