Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a marker lamp control device capable of transmitting to a marker lamp, control signals for controlling each marker lamp from a power supply apparatus side without using a special signal line or without using a power line carrier system.SOLUTION: Phase control output of a power supply apparatus 1 is switched in a pattern different from a switching pattern at normal time to have a control signal S2 (Fig. 3). Combination of the phase control output by this switching pattern is discriminated on a marker lamp 10 (40) side, and heating means 25 (46) is operated in order to melt snow attached to light projecting window parts 41, 41 of the marker lamp 10 (40).
