PURPOSE:To reduce cost and mounting space by interconnecting one of fixed contacts and a movable contact of a single-pole double throw change-over switch such that two front and rear turn signal lamps of either right left side are alternatively lit. CONSTITUTION:When a movable contact 11 is connected to fixed contacts 12, 14, a change-over switch 1 is manually operated to connect a movable contact 2 to a fixed contact 3. Then a closed loop of a battery 16 contact 11 12 left front turn signal lamp 6 contact 3 2 is completed to light the lamp 6. Then, since other lamps are opened, they are held at the turned-off condition. Next, after a predetermined time, the contact 11 is connected to contacts 15, 13 by the self switching action of a turn signal relay 10 to open the close loop and provide a closed loop of the battery 16 contact 11 13 left rear lamp 7 contact 3 2 to turn off the left front lamp 6 and light the left rear lamp 7. Thereafter, lamps 6, 7 can be alternatively lit by a single switch and a turn signal relay to reduce cost. |
