A vehicle lamp can include a primary light source and a visor for preventing the lamp from falling into a state of false illumination due to incident light from light sources other than the primary light source. The lamp can irradiate light toward a predetermined direction. The visor can be provided at a position close to either the light source or a false light source formed by light from the light source. The visor can include a plurality of grooves extending horizontally on one surface thereof, and the grooves can have a V-shaped cross section. An angle made by two sides forming the V-shaped cross section is preferably an acute angle.
