  • an outer track having first and second upstanding walls connected together in spaced apart relation by a base portion spanning therebetween so as to together define a first retention channel, said upstanding walls each having top and bottom edges, inner and outer faces, and a downwardly facing first barrier portion;

    a receptacle having first and second side walls connected together in spaced apart relation by a spanning portion spanning therebetween so as to together define a second retention channel, said side walls each having top and bottom edges, inner and outer faces, an upwardly facing second barrier portion, and a downwardly facing third barrier portion, and being shaped and dimensioned to fit closely between said first and second upstanding walls of said outer track;

    a protective top cover having first and second side walls connected together in spaced apart relation by a lens spanning therebetween, said side walls each having top and bottom edges, inner and outer faces, and an upwardly facing fourth barrier portion, and being shaped and dimensioned to fit closely between said first and second side walls of said receptacle;

    a lighting element shaped and dimensioned for placement between said receptacle and said top cover;

    wherein, at least one of said first and second side walls of said receptacle and said first and second upstanding walls of said outer track is movable between a respective locking position where said second barrier portion is in intimate engagement with said first barrier portion and a respective unlocking position where said second barrier portion is removed from intimate engagement with said first barrier portion; and

    wherein, when said lighting track is assembled, said protective top cover is in place in said second retention channel of said receptacle and said receptacle is in place in said first retention channel of said outer track, such that said first and second barrier portions intimately engage each other in interfering relation and said third and fourth barrier portions intimately engage each other in interfering relation, so as to thereby retain said receptacle in releasable locking engagement within said outer track and to thereby retain said protective top cover in releasable locking engagement within said receptacle.
