| 摘要 |
A stop-light system for motor vehicles for providing a variable light indication to the operator of a trailing vehicle including means responsive to the driving velocity and applied brake pressure for controlling the energization of the stop-lights to provide a variable light indication which varies from a weak to a strong indication with decreasing driving velocity and/or increasing brake pressure. The variable light indication is in the form of an increase in the lighted-up surface and/or an increase in the intensity of the stop-lights.
