Abstract
A tire pressure-monitoring device (TPMD) directly mounted onto an air-pumping inlet-stem on a tire. The TPMD includes a light emitter connected to a battery through an electrical connecting loop wherein the electrical connecting loop comprising a plurality of electrical conductive structural components and at least two of the structural components are physically separated in a normal tire pressure condition and connected in a low pressure tire pressure condition for providing power to the light emitter for emitting a low tire pressure warning light.
