CONSTITUTION:The relay and the timer 1 are connected to the lamp and horn circuit, and a set gear 3, a locking cam 4 and an electromagnet 5 are provided as a lock mechanism. Generally, by the set gear 3 and the locking cam 4, the timer is set and locked to a certain time. When necessary as in case of emergency or the like, the electromagnet 5 is actuated to attract the locking cam 4 to release the lock. Thus, the timer 1 is driven and after the lapse of a certain period the lamp and horn circuit is closed to light a lamp and to give a warning, thereby enabling the specification of the automobil in problem. |
