The present invention includes an electrical adapter switch assembly for bypassing the door light circuit on a Jeep TJ.RTM. when the driver and/or passenger door is removed. The defeat switch is a plug in electrical adapter designed to bypass the door light circuit on a Jeep TJ.RTM. when either or both front vehicle doors are removed. In use, the adapter is inserted in place of the existing door fuse. A slider switch mounted on the cover of the adapter is placed in an On/Normal position where the door light circuits function in the normal manner. Conversely, when placed in an Off/Remote position, the fuse is effectively removed from the circuit and the door lights will not operate even if the vehicle doors are removed. A remote plug allows for a remote mounted switch, perhaps located on the dashboard to be wired in to control the door light circuits.
