Abstract: By providing, for use in a repair-truck installation, a lighting bar including the combination of a lamp having a rectangular, spreading beam with a lamp having a round flooding beam, the combination being supported rotatably from a pole which is attachable to a truck on which the combination is being carried, displacing the lamp with the rectangular, spreading beam from the axis of the vertical supporting pole by a distance sufficient to permit the rectangular beam to illuminate a significantly large work area local to the truck while the lamp with the round beam is supported at a lesser distance from such axis to permit illumination of a work area remote from the truck, repair work, for example on a remote gas meter may be conducted simultaneously with related preparatory work at the truck without light switching or transporting, thus increasing the efficiency of the repair personnel and the accuracy of their work.
