Background and Objects of the Invention
Conventional headlight or similar installations consist of separate structures. The support structures are attached to vehicle parts within the body shell but not directly connected to or carried thereby, which support structures are positioned to mount the light units in openings formed in the shell. Separate ornamental frame structures are then required to cover the gaps between the margins of the light units and the margins of their shell openings. Each assemblage is thus structurally complicated and difficult to install or repair. And headlight adjustment requires removal of the trim frame structures.
It is accordingly the principal object of this invention to simplify headlight or like installations by providing a combined support and trim ring therefor, which is easily installed in and supported by the margins of shell openings for the installations.
It is another object to provide a combined trim ring and support plate for a headlight installation in which the headlight can be beam-adjusted by a slender rod-like tool insertable through the support plate without disturbing the ring or the plate.
It is further object to provide a pair of interconnected adaptor plugs whereby a pair of high-low-beam lights can be installed without cutting or splicing conventional connector units for single high-low-beam lights.
Other objects and advantages of the disclosure will appear as the following detailed description proceeds.

Detailed Description
With reference now to the drawings, the numeral 11 designates the combined trim ring and support plate (hereinafter called the support plate). Said plate has a rearwardly turned peripheral flange 13 of varying width if and as needed to fit the contour of the body shell 15 (FIG. 3). The edge of the flange 13 is capped by a finish-protecting and weather-proofing resilient rubber or plastic channel element 17 (shown only in FIG. 3 but omitted elsewhere for clarity). The support plate 11 is fastened to the somewhat overlapped margins of the assemblage-receiving aperture 19 (FIG. 3) in the body shell 15 by four self-tapping screws 21.
The support plate has mounted thereon a pair of conventional sealed-beam lamps 23 and 24. Lamp 23 has two filaments and three terminals for high or low beam, while lamp 24 has a single filament for high beam only (FIG. 2), which can be connected to a conventional three-wire connector (not shown) for a single two-filament headlight by the adaptor 25. The adaptor 25 comprises a two-terminal female coupler 27 and a three-terminal male-to-female coupler 29, which couplers are interconnected by short flexible leads 31. The male terminals of the coupler 29 connect with the terminals of said conventional connector.
The lamps 23 and 24 are housed in metallic shells 33 and 34, respectively, and are retained therein by sheet-metal rings 35 having inturned flanges 37 embracing the margins of the lamp faces. The shells and the rings have mating outturned integral tabs 39 (FIGS. 3 and 4) interconnected by self-tapping screws 41 to form a lamp-embracing housing.
The shells 33 and 34, and thereby the lamps 23 and 24, are each beam-adjustably supported in shape-conforming cutout areas in the support plate 11 by a three-point suspension arrangement. Each suspension arrangement comprises three omega-shaped straps 43 spot-welded to the support plate 11 with its bight portion spaced from the support plate and apertured to receive an anchoring screw 45 in one aperture and two beam-adjusting screws 47 in the other two apertured straps.
The screws 45 also pass through apertures in tabs 49 welded to the shells 33 and 34. Coil springs 51 co-operate with the screws 45 to permit in-out positioning and beam-angle adjustments of the lamps. The screws 47 have enlarged heads 53 circumferentially grooved to engage over the edge of laterally open slots in their co-operating straps 43. The screws 47 also pass through plastic split nuts 55 which are fixed to the shells 33 and 34 by being press-fitted into apertures in angle brackets 57 riveted or welded to the shells 33 and 34. The heads of the screws 47 are kerfed to receive a screw-driver-like adjusting rod (not shown) inserted through small holes 59 (FIG. 4) in the support plate 11 axially aligned with the screws 47.
