Abstract: A lamp, whether HID or other, can be conveniently held by with slip ring that compresses flexible arms against the lamp end. The arms are formed to conform on and inner side with and exterior portion of the lamp. On their exterior side of the arms are formed to mate in compression with a slip ring. By tapering the arms with respect the slip ring, and increasing pressure can be induced that flexes the arms to hold the lamp in place. The slip ring can be further formed to bind the slip ring with three clamp arms, and thereby resist disengagement of the structure once assembly is completed. The result is a securely held lamp accurately held by inexpensive parts adaptable to rapid machine assembly.

Abstract: An adjustment linkage for vehicle headlamp having housing coupler, adjustment shaft, shaft seal, and threaded coupler for coupling to a pivotable reflector is disclosed. The adjustment linkage is designed to be operated by a Philipshead screwdriver used as a gearing. No permanent gear box is formed in the linkage. A minimal linkage is formed that is accessible from the top of the headlamp module by the length of the screw driver. The adjustment linkage is water sealed to accommodate rotation and pivoting of the linkage.
