Abstract
A vehicular lamp forms a low-beam distribution pattern by combining light radiated from a first unit and a second unit. A brightness decreasing element is provided on a reflective surface of a first main reflector in a sub-unit of the first unit. Thus, for the low-beam distribution pattern formed by the first unit and the second unit, among a peripheral end portion of a cut-off line forming pattern formed by the sub unit, a low luminance portion with a partially reduced brightness is formed at the border of both right and left end sides that upwardly overlap with a portion of a diffusion area forming pattern.
