Abstract: A trouble lamp is constructed to provide a sliding movement between a light bulb and a reflector shield with slip friction fit between parts such that they may be manually positioned to provide the quality and amount of light desired by the operator.

Abstract: A rectangular seal beam lamp and single-point universal support assembly for vehicles that is replaceable as a unit and that has high shock-absorbing characteristics. The lamp includes a rectangular plastic paraboloidal reflector having an integral single polygonal support post that carries a slotted rubber ball member which forms part of the mount for the lamp. The ball is compressed and clamped against the post by a pair of mating semi-spherical cooperating fastener elements that support the lamp unit and permit adjustment of the lamp beam in any direction by a single adjustment.

Abstract: Light mounting tapes receiving electric light sockets of the type commonly used for Christmas decorations are provided in elastic form so that they may be stretched as desired between mounting fasteners, as for example around a door or window frame. The tapes provide a plurality of receptacles along their lengths. The tapes can be furnished in segmented lengths and easily secured together in series to provide a desired overall length. The elastic properties of the tapes facilitate stretching them into taut condition for fixedly positioning the electric lights mounted in the receptacles thereof.

Abstract: Mounting device for rotatable adjustment of asymmetric reflector within luminaire housing to vary the light distribution from the luminaire. The mounting device includes a plurality of brackets circumferentially spaced around the lower portion of the dome-shaped luminaire housing for supporting the circular rim of the asymmetric reflector, which is formed with a corresponding plurality of recesses for clearing the brackets when the asymmetric reflector is inserted in or removed from the luminaire housing. Adjustable clamps are arranged adjacent the brackets for securing the reflector in the desired rotational position.

Abstract: Luminaire lamp support device for vertical and angular adjustment of vertically-mounted lamp. The device includes a pair of spaced L-shaped plates secured at their bottom to the luminaire reflector in which the lamp is positioned and secured at their upwardly extending legs to an inverted U-shaped hinge bracket to which the lamp socket is secured. The hinge bracket is adjustably secured to the L-shaped plates for pivoting thereon about a horizontal axis. The socket is adjustably mounted on another U-shaped bracket secured to the hinge bracket for adjustment of the socket along a substantially vertical axis.

Abstract: Converter means for converting a side marker light for a vehicle such as a trailer to a combination side marker and clearance light comprises an adapter assembly for repositioning the ligh bulb and a multi-sided translucent lens for replacing the original flat lens of the side marker light.

Abstract: A baseless light bulb is locked into a one-piece molded base and the base provides mechanical and electrical connection of the light bulb to a circuit board.
