ABSTRACT:
A system for controlling the power supply to an automotive vehicle lamp in which two switch means are connected in series with each other, an interior room lamp in the vehicle compartment, and the power supply, i.e., a vehicle battery, one switch means being closed when a detachable back door is open and open when the back door is closed and the other switch means being open when the back door is detached from the vehicle body. Therefore, the interior room lamp is turned off when the back door is detached even though the first switch means is closed. Consequently, wasteful power drain on the vehicle battery can be avoided when the back door is detached.
