The Electric Searchlight is a deployable item that has not been implemented into Rust yet. It works much like a spotlight, and has a more improvised, welded together look.
NOTE: The Savas Island map present in the current Rust has these, but they are static, stationary, indestructible and cannot be controlled by a player.
