A power supply route for a light source includes a first route that closes when a microcomputer is operated and a second route that opens when the microcomputer is operated. When the microcomputer stops operating, the power supply route of the light source is automatically switched from the first route to the second route. When the microcomputer is operated and a position lamp switch is turned on, current is supplied to the light source through the first route. When the microcomputer stops operating and the position lamp switch is turned on, current is supplied to the light source through the second route.
