摘要： A vehicle lamp can include a light source, a reflector having a parabolic reflective surface for reflecting light beams from the light source, and a lens formed in a generally rectangular shape (i.e., square, rectangular, substantially square, substantially rectangular). The lens can include a plurality of lens cut portions for diffusing the generally parallel light beams from the reflector. The principal optical axis of the vehicle lamp can be aligned with the center of the lens. A plurality of ridge lines or valley lines can extend radially from the principal optical axis to divide the generally rectangular lens into at least a first lens cut portion, a second lens cut portion, a third lens cut portion, and a fourth lens cut portion. The first lens cut portion can be a substantial mirror image of the second lens cut portion, and the third lens cut portion can be a substantial mirror image of the fourth lens cut portion. Part of the parallel light beams from the reflector can be diffused in the left and right directions through the first and second lens cut portions, and at the same time, part of the parallel light beams from the reflector can be diffused in the up and down directions through the third and fourth lens cut portions.
