摘要
The early warning system for traffic jams uses the third raised brake light as an intermittently flashing light to warn of traffic jams or stops. The additional light can be a retrofitting or original fitting for new vehicles. The lights can be fitted to vehicle trailers. The circuit uses switching diodes (D) and relays (J1) to control the additional light.
