A vehicle lamp for installing on a vehicle includes a projector lens, a reflector, a first light emitting element, a shield, and an optical grating unit. The projector lens has a light entry surface and a light exit surface. The first light emitting element is adjacent to a first focal point of the reflector, and is for emitting light towards the reflector. The shield is for blocking a portion of the light that is emitted from the first light emitting element to form a cut-off line in a light distribution pattern. The optical grating unit is for reflecting at least a portion of the light that has passed a second focal point of the reflector and that has not passed through the light exit surface of the projector lens.
