Abstract
A lamp system includes a road surface drawing lamp that illuminates a road surface with a beam BM, and a lamp controlling unit that controls the road surface drawing lamp and draws, with the beam BM, a pattern PTN on the road surface ahead of a vehicle. The lamp controlling unit draws a first pattern before a start of a predetermined event and draws a second pattern at the start of the event. The first pattern includes first information to be presented in advance to a driver to allow the driver to respond to the event, and the second pattern includes second information corresponding to the event.
