Claims

[Scope of utility model registration request]

a tail relay having an excitation coil and a normally open contact; a tail lamp having one end grounded and the other end connected to a power supply via the normally open contact; and a tail lamp having one end grounded and the other end connecting the excitation coil. The lamp is equipped with a column switch connected to the power supply via the power supply, and a courtesy switch that is turned on when the door is opened and opened when the door is closed, thereby controlling the current flowing from the power supply to the room lamp and causing the room lamp to flicker. In the lighting circuit, there is a timer that outputs a timer output that becomes high level for a certain period of time from this point on when the courtesy switch linked to the driver's side door is opened, and the potential of the excitation coil of the tail relay and the timer output of the timer. and a transistor that is interposed between the excitation coil and ground and is driven by the output of the AND gate and becomes conductive. Characteristic car footwell lighting circuit.
