<p>PURPOSE:To make the containing operation of a head lamp avoidable when a key switch is turned off under exposed condition of the head lamp and subsequently turned on again, by providing a timer circuit for producing an output signal for a predetermined time when a lighting switch is switched from on to off. CONSTITUTION:Motors MT1, MT2 for exposing/containing right and left head lamps L1, L2 are provided and sliding pattern switches SSW1, SSW2 interlocked with said motors are also provided. Up relays UR1, UR2 and down relays DR1, DR1 are connected to the top dead center and the bottom dead center of the sliding pattern switches SSW1, SSW2. A relay contact (try) of a timer relay TRY is placed in the down side line DL of a lighting switch LS where NC contact of said contact (try) is connected to the down relay DR1, DR2 side while NO contact thereof is connected to a retractable timer circuit RT. Furthermore, an up holding timer circuit UT for producing an output signal for a random time when the lighting switch LS is switched from on to off is provided.</p> |
