An electrical raceway for installation in an illuminated double-sided sign box is in the form of an elongated and hollow structure which provides reinforcement for such a sign box and a housing for electrical conductors. Opening zones, usefully in the form of knock-out discs are provided in the side walls of the raceway for the mounting of lighting fixture receptacles while aligned openings in such side walls are provided for the disposition therethrough of an elongated lighting tube terminally fitted in receptacles on a pair of such raceways disposed on opposite sides thereof. Deformable tongues formed in such side walls at such openings can be bent toward the opposite side walls to provide barrier members to prevent the electrical conductors within such a raceway coming into contact with a lighting tube extending therethrough.
