Nite Saber II plow lights were optional in years past, and are now standard, becoming standard in 2013. They have a high beam bulb, and a low beam bulb. The original design had the same mounting on the bottom as the Nite Saber lights. Then they went to a bracket much like a fog light. They have two Stainless Steel Bolts that are used to adjust and secure the lights. They are the ONLY plow light with Stainless Steel hardware. They also use all of the same wiring, Modules, and Adapters that the Nite Saber Lights use. You can unplug a Nite Saber light and replace it with a Nite Saber II with no other modifications.
As of the Fall 2016, the Nite Saber II have been replaced by the Nite Saber III. They are nearly identical, except the Nite Saber III have a smooth lens, and an internal steel bracket to make the housing stronger.
