Abstract: The present invention pertains to lighting device systems or methods applicable to off-road utility vehicles. The concepts include light sources for light beam production, a housing enclosure that encompasses internal elements and includes opposing front and rear portions. Inventive concepts further include a heatsink arrangement along an outer surface of the rear portion via a fastening system that is configured to transfer generated heat from the light sources and includes a sealing member with fasteners for securing the heatsink through the housing such that the sealing member becomes positioned between the heatsink and interfacing housing structures.

Abstract: A light system comprising: (a) a vehicle connector configured to connect to a vehicle; (b) a light connector in communication with the vehicle connector, the light connector being movable relative to the vehicle connector; and (c) a bias member connected to the light connector and extending into contact with the vehicle connector so that as the light connector is adjusted the bias member creates a bias force to move the light connector away from the vehicle connector or the bias member is compressed to store energy.
