Modulated intensity flasher for vehicle brake light with lockout |
摘要 |
A method and apparatus for brightening and dimming a brake light of automotive vehicle for enhanced display indication of braking includes a pulse width modulation unit to be electrically connected to a brake lamp for sequentially modulating the supply energy to the lamp to generate a brightening and dimming of the lamp. A time extent of the modulation is detected so that the modulation can be stopped after a preselected time period and the light will be continually on as in a conventional braking operation After the brake is released by the operator, a second preselected time period for locking out the sequential interrupting is timed down, for avoiding repetitive flashing during stop-and-go traffic.
