PROBLEM TO BE SOLVED: To provide a lighting-control system realizing simplification of a system configuration and cost reduction by reducing the number of components and that of harnessing wires.SOLUTION: A lighting-control system includes: a lamp L-HL 1 as core; a separately-configured lamp C/DL 2; and a body ECU 3 for outputting a lighting control signal for controlling lighting of the aforementioned lamps. The lamp L-HL 1 includes: a first LED drive circuit 15 for lighting a light source 12 of the lamp itself; and a control circuit 16 for outputting a required lighting signal on the basis of the lighting control signal. The separately-configured lamp C/DL 2 includes: a second LED drive circuit 22 for lighting a light source 21 of the lamp itself. The first and second LED drive circuits 15, 22 perform lighting operations on the basis of a lighting signal output from the control circuit 16. |
