<p><P>PROBLEM TO BE SOLVED: To provide a lighting control circuit capable of preventing light emission unevenness in illumination for a tail lamp generated when an LED is used as a lamp light source and lighting a filament for a stop lamp as illumination for the tail lamp when a double filament light bulb is used as the lamp light source and the filament for the tail lamp causes disconnection. <P>SOLUTION: A lamp discriminating means 22 detects a current value of a power supply line 28 for the tail lamp to discriminate type of the lamp light source connected with a socket part 21. A light reducing control means 23 modulates a current flowing in the power supply line 28 for the tail lamp in accordance with a control signal from the lamp discriminating means 22 to make it flow into a power supply terminal 24 for the stop lamp in order to light the lamp light source connected with the socket part 21 by reducing light. <P>COPYRIGHT: (C)2004,JPO</p> |
