ABSTRACT:
A discharge lamp starter includes a discharge lamp that is lit at a luminance corresponding to power supplied, and a discharge lamp start control unit. The discharge lamp start control unit, receiving a signal indicating an on state only from a first switch, causes the discharge lamp to perform daytime running light by supplying first power to the discharge lamp to start lighting, followed by supplying second power smaller than the first power to the discharge lamp to maintain lighting. Receiving a signal indicating an on state only from a second switch, the discharge lamp start control unit causes the discharge lamp to perform nighttime running light by supplying third power greater than the first power to the discharge lamp to start lighting, followed by supplying fourth power smaller than the third power and greater than the second power to the discharge lamp to maintain lighting.
