<p>PROBLEM TO BE SOLVED: To require no dedicated special switch to be installed at a driver's seat by setting an auxiliary lamp to the standby state when vehicle width lamps are lighted, and turning-on the auxiliary lamp after a specified number of passing actions are taken within a fixed set time. SOLUTION: When vehicle width lamps 1 are lighted, electric power is applied to various circuits through the internal structure power circuit 7 of a control device. When upper headlights 2 are lighted, a timer circuit 8 starts operating and sends an output for a predetermined time. A counter circuit 9 starts counting the number of the lighting times of the upper headlights 2 and continues the counting until the predetermined time of the timer circuit 8. When the blinking of the upper headlights 2 reaches the specified number set in advance, a holding circuit 10 is operated to hold the state. A relay 5 is operated by the output of the holding circuit 10 to connect an on-vehicle battery 6 and an auxiliary lamp 3. When the auxiliary lamp 3 is to be turned off, the upper headlights 2 are merely blinked specified times within the set time.</p> |
