摘要： In an operation control system, when a selection manipulation for blinking one of turn lamps is inputted using an in-vehicle combination switch, a frequency signal corresponding to the selection manipulation is outputted from a signal oscillation section to a signal transformation section via a common control line. In addition, the signal transformation section causes, out of two individual signal lines, an individual signal line corresponding to the inputted frequency signal to be in an active state. One of driver sections blinks one of turn lamps corresponding to the individual signal line being in the active state. It is noted that a drive control section stops temporarily operations of the turn lamps while both the input signal lines are in the active state.

摘要： Left and right turn lamps are used as lamps in a daytime travel of a vehicle. When a first daytime turn-on requirement is satisfied, i.e., when an ignition switch is ON, a left-hand contact of a turn switch is OFF, a right-hand contact thereof is off, and the like, a left front turn lamp and a right front turn lamp are turned on as the lamps in the daytime travel, based on signals outputted from first and second AND logic circuits. When the left-hand contact of the turn switch is turned on in this state, the left front turn lamp flashes, based on a signal outputted from a flasher circuit, whereas the right front turn lamp keeps a turn-on state. On the other hand, when the right-hand contact of the turn switch is turned on, the right front-turn lamp flashes, based on a signal outputted from the flasher circuit, whereas the left front turn lamp keeps a turn-on state.
