Abstract

An in-pavement airport lighting fixture includes a housing, a feed-through assembly, and a threaded bolt that extends through the housing to secure the housing to a base unit. The feed-through assembly carries a lamp and positions the lamp in the housing. The threaded bolt is coupled to the housing such that the housing is lifted by upward motion of the bolt as the bolt is disengaged from the base unit. The housing further includes at least one boss and the feed-through assembly includes a connector surrounding an upper portion of the feed-through assembly. The connector mates with an outer surface of the boss when the upper portion of the feed-through assembly is positioned against an inside surface of the boss.
