Abstract
Abstract A portable light assembly conformed for excitation from the cigarette lighter outlet of an automobile comprises two light housings each universally pivoted from a central handle assembly. The central assembly includes opposed pivot fittings from which two laterally disposed swivel blocks are pivoted, each swivel block in turn pivotally supporting a corresponding light. In this form the alignment of each light may be individually selected to produce any desired beam pattern, the same pivotal freedom providing for a collapsed alignment where the lens portions of each light are protected from damage.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
210 words
A portable lighting assembly conformed for electrical excitation and pivoted to collapse for storage, comprising: a substantially rectangular center section including a first and second lateral edge surface each provided with an opposed pivot mount proximate the center thereof; a first and second swivel block arranged for pivotal engagement to the respective ones of said pivot mounts in said first and second edge surfaces each said swivel block being of an elongate conformation substantially equal to the corresponding ones of said first and second lateral edges; pivotal engaging means deployed to engage said first and second swivel block to the corresponding ones of said pivot mounts in said first and second lateral edge surfaces, said engaging means including manually securing operable means for selectively fixing the pivotal motion of said first and second edge surfaces; a first and second light assembly of substantially rectangular shape hinged along one edge thereof from the corresponding ones of said first and second swivel blocks for articulation from a first position adjacent said center section to a second position distal thereof; and manually operable fixing means deployed between said first and second light source and the corresponding ones of said first and second swivel blocks for selective fixing of the relative hinging articulation thereof.
