Abstract: Systems and techniques are described to provide a bulb insertion structure of a vehicular lamp which allows bulb replacement and accurate positioning of a bulb with respect to a reflector. In general, in one implementation, a bulb insertion structure of a vehicular lamp includes a plurality of fixing protrusions formed on an outer periphery of a rear end portion of a cylindrical socket fixture fixed in a bulb insertion hole of a reflector; a plurality of engaging protrusions formed on an outer periphery of a focus ring provided on a bulb and corresponding to the fixing protrusions; and a cup-shaped socket covering the outer periphery of the socket fixture from the rear, the socket incorporating a spring for pressing forward the rear end portion of the accommodated bulb, and having an outer peripheral wall provided with, at multiple locations corresponding to the fixing protrusions, an engaging notch (J-slot) for holding the engaging protrusion and the fixing protrusion overlapped together.

Abstract: A vehicle lamp including light sources, a reflective mirror for effecting desired light distribution by reflecting light emitted from the light sources and a lens disposed in front of the reflective mirror. In the vehicle lamp, the reflective mirror has a dummy portion which makes no contribution to effecting light distribution and is exposed to the outside through the lens, and an indicative mark for identifying the lighting device is formed integrally with the dummy portion. As the indicative mark can be visually recognized from the outside through the lens, the indicative mark needed not be formed on the lens. When lighting devices having different light distribution characteristics are provided, it is only needed to produce reflective mirrors respectively having corresponding indicative marks and the rest of the parts including the lens and the lamp body can be provided for common use.

Abstract: A rear-deck stoplight for automotive use is designed such that light emitted therefrom and reflected from the interior and exterior surfaces of the rear window passes beneath the rearview mirror of the vehicle so as to not hinder the driver's vision while braking. The light is separated from the rear window by a gap. A lens covering the lamp is generally angled with respect to the rear window, and a shade at least partially bounds said lens. The gap size, the lens angle and particularly the shade height are selected so as to limit reflected light to a region below the height of the rearview mirror.

Abstract: A shade 17 surrounding the lens 20 of a centered "high mount" vehicle stoplight has an extension 17aat its upper end which blocks light diffused/dispersed by the lens and reflected inwardly by the rear window 1 to prevent such light from reaching the driver's eyes via the rearview mirror. The extension is sufficiently long to block light running substantially parallel to the lens and striking the window at a maximum angle .THETA., whereby it will inherently also block the remaining light striking the window at a smaller angle.
