<p>PROBLEM TO BE SOLVED: To contrive the electric power saving, the anti-dazzle effect on the driver of the following car, and the cost reduction in heat resistance measures. SOLUTION: When the predetermined time has passed since a stop lamp L lit, a timer circuit A operates to output the voltage to b, and a transistor Tr is closed through a constant voltage circuit, and the stop lamp L is turned off. As these, even in a state in which a brake pedal BP is kept depressed, when the vehicle completes the stopping and needs not to let the following car know that the vehicle is during the braking operation, the stop lamp L is turned off. As a result, battery Vcc consumption decreases. This does not give dazzle to the driver of the following car. The temperature rise in the stop lamp L is suppressed, and the cost reduction in heat resistance measures is achieved.</p> |
