PURPOSE:To eliminate the variation of the lighting time by attaching an automatic device to a light control switch. CONSTITUTION:A current is taken from a fuse box 2 passing an ignition switch 1 and the current which has the voltage reduced by a transformer 8 flows to an exposure meter 6, and an automatic switch 5 is operated to flow it to a light control switch 9. That is, the current flowing to the fuse box 2 flows to the transformer 3 and a by-pass 4. The current flowing to the by-pass 4 passes the contact of the automatic switch 5 to operate the switch 9. Meanwhile, the current which has the voltage reduced by the transformer 3 operates the exposure meter 6. Thus, problems of forgetting to switch on a light, an individual difference of brightness, and the variation of the lighting time are resolved.
