<p>PURPOSE:To prevent an undersirable current leakage, by controlling to avoid the formation of a series lighting circuit when a burning out of a fuse is detected. CONSTITUTION:A pair of headlamps LH and RH are connected to a power source through fuses F2 and F3 respectively. The headlamps LH and RH furnish a series lighting circuit to feed the current connected in series to the power source or a parallel lighting circuit to feed the current parallel, and can be converted by a light switch device 1. When a series connection command is given by the light switch device 1, the series lighting circuit is formed by a lighting control device 2 and connected to the lamps LH and RH. In this case, if the fuse F2 is burned out, relays 21 and 22 do not operate and the series lighting circuit is not formed. And if the fuse F3 is burned out, a transistor 23 is turned off, the series lighting circuit is not formed, and undesirable current leakage can be prevented.</p> |
