ABSTRACT:
A portable light support apparatus having a telescoping mast unit. The apparatus includes a mast support unit (11) that provides a housing unit (14) for containing a generator unit and a hydraulic operating system, and a wheel assembly (16) and tongue unit (17) for facilitating portability of the housing unit (14). A telescoping mast unit (12) pivotally connects to the mast support unit (11) and provides for a vertical lock unit (32) and a safety lock unit (34) to prevent the apparatus from elongating unless in a vertical position. A rotating light bar (86) connects to the top of the telescoping mast unit (12) such that electric lights mounted thereon can be rotated from a remote position.
