PURPOSE:To aim at improvements in operation efficiency, by assembling a lighting circuit for car light use, having such a system as being correspondent to different legal regulations pertaining to a rear fog light. CONSTITUTION:A switch unit 11 comprising head lamp switches 11a and 11b switching on and off head lamps 2a-3b and selecting from a main light to a dimmer and vice versa is a switch system that is solidified with a rear fog light controlling switch 11c being turned to ON when these switches 11a and 11b are set to the main side (M side). When these switches 11a and 11b are connected to the M side, a power source is fed to a main filament MF among these head lamps 2a and 2b, 3a and 3b, and on the other hand, when they are connected to the dimmer side, the power source is fed to each dimmer filament DF of these lamps 2a and 2b. In the switch 11c, its switch contact terminal is being drawn out to each of connector terminals 25 and 26, therefore this terminal gets ready for one being connected to A and B and the switch unit that is not connected to them whereby it corresponds to two kinds of legal regulations. |
