<p>PURPOSE:To provide electric saving, in a unmanned carrier provided with a brake light which lights up under a braking condition, by arranging a lights out means which puts off the brake light forcibly at a prescribed time after the vehicle detects the braking condition. CONSTITUTION:When braking is applied to a vehicle by braking (not illustrated) and a control light switch 18 is turned on, a brake light 20 lights up and a timer 17 comes into action. In the timer 17, a prescribed time, within which a worker around the vehicle can verify fully that braking is applied to the vehicle, is set. After the prescribed time has passed, it outputs a signal to a ground circuit 16. It is thus possible for the ground circuit 16 to energize a relay 15 and turn off a normally closed contact 19, putting out the brake light 20 forcibly.</p> |
