The present specification discloses a remotely operated light bar tilting system that adjusts the tilt angle of a light source about an attachment base mounted to a vehicle or other structure. A remotely operated light bar tilting system disclosed herein comprises an actuator coupled to and rotates with the light source to adjust the tilt of the light source by pushing or pulling on a linkage assembly that transmits a force from the actuator to an attachment base. The linkage assembly can include a ternary link or other similar link or assembly of links that can transmit force to the attachment base for tilting the light source. The tilting mechanism is entirely supported by the attachment base creating a compact system that does not require the actuator be mounted to a separate base on the vehicle.
