Early warning system for traffic jams has third raised brake light on vehicle used intermittently as jam warning light

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.
