Abstract
Light from a headlight is prevented from being diffusely reflected on a road surface and reaching an oncoming vehicle. Provided is a lamp control method of controlling a lamp including a lamp unit that projects light over a predetermined range and a driver that turns on and turns off or dims a light projection range of the lamp unit in predetermined units. The lamp control method includes a step of obtaining a reflection region on a road surface where the light projected from the lamp unit is regularly and diffusely reflected by the road surface and reaches a driver of an oncoming vehicle or a preceding vehicle, and a step of controlling the driver so that the light projected onto the reflection region from the lamp unit is turned off or dimmed.
