Automatic activation device for motor vehicle emergency breakdown lights

摘要

The emergency indicator lights of a car are automatically activated through a relay and a pressure switch by a particular brake hydraulic pressure. The system is combined electrically or mechanically with the ABS, a collision alarm and the airbag release mechanism. It is also combined with an automatic receive-transmit system whereby when a certain radio signal early-warning signal for weather or traffic ahead is received, the transmitter automatically releases another signal for the lamps. High-level brake lamps are also activated by the system.
