Claims

[Scope of utility model registration request]

Step lamps installed on each front and rear door are connected in series to a power supply, and these step lamps are connected to each door switch so that they are lit by a door switch that is linked to the opening operation of the front and rear doors. In the door step lamp circuit, a room lamp is connected in parallel to form a front door one lighting circuit, and in the rear door step lamp circuit, a half door warning lamp is connected in parallel to form a rear door one lighting circuit. In addition, the front door switch and the rear door switch are separated in terms of circuits for the ground side connections of the front door lighting circuit and the rear door lighting circuit, and when the rear door is opened and the rear door switch is closed, A door opening/closing lighting circuit for an automobile, characterized in that a diode is connected to the front door lighting circuit to prevent each lamp from lighting.
