<p>PURPOSE:To prevent exhaustion of a battery by supplying current to a lighting control means for a high-mount lamp etc. only when a stop lamp switch is on, in case the back door is removed and ignition switch is off. CONSTITUTION:In case a back door is open (even removed), a back door switch 11 is turned on, and in case an ignition switch 23 is on, exciting current flows in a coil 10a via a diode 21, and terminals a, b of a relay switch 10b are put in connection. Accordingly a stop lamp 6 and a high-mount lamp 9 on cabin side are lit when a stop lamp switch 7 are made. When the switch 23 is off, on the other hand, no current is supplied to a relay 10 until the switch 7 is made, to check exhaust of battery 8. When the switch 7 is made, current is supplied to said coil 10a via another diode 22, and alike the two lamps 6, 9 are lit.</p> |
