Abstract
A light tilting apparatus usable with an extendable light. In one embodiment, a mobile lighting system includes a tiltable light assembly mounted to an extendable tower on a trailer. The tiltable light assembly includes one or more lights fixedly mounted to a tilting member pivotably mounted to the extendable tower. A linkage operably connected to the tilting member at one end has a catch on a distal end. A linkage regulator attached to the extendable tower has a guide portion for the linkage to pass through as the extendable tower is extended and retracted. The linkage regulator is configured to engage the catch on the distal end of the linkage when the extendable tower reaches a preselected extension position restricting further motion of the linkage in the direction of tower extension. The linkage causes the tilting member to pivot and rotate the lights downward with continued extension of the extendable tower past the preselected extension position. Retraction of the extendable tower back to the preselected extension position, accordingly, results in causing rotation of the lights upwardly.
