<p>PURPOSE:To make a unit compact by applying the constitution wherein the first and second relay means while either means being actuated upon turning on a turn signal switch, are made to operate concurrently upon turning on a hazard warning switch. CONSTITUTION:When a turn signal switch 15 is selected, for example, to the side of a selector contact 15b, a transistor T2 is turned on and another transistor T1 is turned on via a control circuit 5. Furthermore, the relay contact 21a of a relay 21 is closed and a left turn signal lamp 3 lights. Then, the control circuit 5 starts the charging of a capacitor CT and when the predetermined time governed by the time constants of the capacitor CT and a resistor RT passes, the transistor 1 is turned off and the left turn signal lamp 3 is turned off. Consecutively, the aforesaid operation is repeated and the turn signal lamp 3 is made to flash. On the other hand, when a hazard warning switch 16 is turned on, both transistors T2 and T3 are made electrically live, and right and left turn signal lamps 3 and 4 are made to flash synchronously.</p> |
