The second telescoping unit is telescopically received in the first telescoping unit to configure the expandable light tower to have retracted and extended configurations. The light tower further includes a light-mounting assembly mounted to the second telescoping unit and a mounting assembly coupled to the first telescoping unit and adapted to mount the telescoping assembly to a hitch of a mobile unit. The mounting assembly enables the telescoping assembly to pivot about a transverse axis.
