ABSTRACT:
An elevated airport runway, taxiway, or threshold edge light with a glass dome that is so positioned with respect to the light source so as to correct for variations in thickness of the base of the glass dome as the result of the glass-making process. The glass dome is sealed into an overhanging cover which preserves the integrity of the interior of the light against adverse weather conditions and the support base on which the cover is positioned is provided with a ball joint so as to permit quick and easy elevation and azimuth positioning of the base in the field. The base is also provided with a vertical support for a snow flag.
