ABSTRACT:
An improved liquid level detecting and indicating system for vehicles comprising a pair of liquid level detecting elements which are arranged in opposite positions on the detecting level of a liquid in a liquid container installed in a vehicle, whereby when each of the liquid level detecting elements sends a signal indicating that the liquid level has dropped below a reference liquid level, an indicator is brought into operation. In this way, the level of liquid can be accurately detected and indicated without being influenced by the inclination or vibration of a vehicle body.
