A vehicle lamp having a hollow body lens unit constructed by integrally forming a lamp body and a front lens which constitute a lamp chamber, a light source provided in the body lens unit, and a diffusion step such as a cylindrical step having step elements, each of which has constant directivity, the diffusion step being provided on the outer surface of the lens portion of the body lens unit. The step elements of the diffusion step on the outer surface of the lens portion are lined up in a predetermined direction and each have directivity, so that the mud and dust do not easily stick to each step element.

Vehicle lamp

A vehicle lamp with a lamp body and a bulb socket portion placed through a bulb fitting hole in the lamp body. A waterproofing annular gasket placed between a flange of the bulb socket and the outer periphery of the bulb fitting hole provides a waterproof seal to the lamp body. The lamp body is integrally formed with a lens such that the bulb fitting hole is the only opening to the outside environment. A transverse cross section of the gasket reveals a sideways gourd-like structure that improves the seal between the flange of the bulb socket and the peripheral edge of the bulb fitting hole.

Vehicle lamp having a waterproofing annular gasket

A vehicle lamp including: a lamp chamber accommodating a reflector for forwards reflecting light emitted from a light source, an inner lens and an outer lens disposed at a front opening of the reflector such that the two lenses are, by projection-and-pit lance engagement, secured to an elongating lens-engaging portion formed along the front opening of the reflector, wherein the inner lens and the outer lens are integrally secured to each other by projection-and-pit lance engagement, and either of the two lenses is secured to (an engagement hole) the elongating lens-engaging portion by the projection-and-pit lance engagement. The number of the visible projection-and-pit lance engagement holes provided for the lens engagement portion and of the reflector, respectively, and arranged to secure the lens can be reduced as compared with a conventional structure.
