Patent ID: 6863424

Claim:
A light bar enclosure comprising: a longitudinally extending base defining a channel bounded by a rear wall and substantially parallel side walls projecting from the rear wall, each side wall having inside and outside surfaces and a forward terminus spaced from said rear wall, each said forward terminus defining a longitudinally extending groove and each said inside surface defining at least one longitudinally extending slot; at least one bracket slidably receivable in said base, said bracket comprising: a foot configured to be longitudinally slidably engageable with and receivable between said slots whereby the bracket, when received in the base, is constrained from movement toward or away from the rear wall of the base; and a lens support arch extending from said foot away from the rear wall of the base when the bracket is received in the base; at least one lens portion having a pair of substantially parallel longitudinally extending edges and configured to fit over the lens support arch of the bracket, with the edges penetrating into laterally opposed portions of the groove defined at the terminus of each side wall when the bracket is received in the base; at least one lens retainer configured to fit over and generally parallel with said lens portion, said retainer extending between a pair of laterally opposed ends and configured such that when said lens retainer is placed over the at least one lens portion and the bracket when the bracket is received in the base, said laterally opposed ends penetrate the groove defined at the terminus of each side wall; a gasket for establishing a water resistant seal between the bracket, at least one lens portion and lens retainer; and fasteners for removably securing the lens retainer to the bracket, whereby the at least one lens portion is engaged between the bracket and the lens retainer with said gasket comprising a layer between the bracket and lens and/or lens and lens retainer.
