It's design allows for Light sticks from various Manufacturers to be mounted in the rear window of some of the most popular 1/2 ton, 3/4 ton and 1 ton pickups used in the todays emergency vehicles.  Comes with two brackets to allow installation of 1 light stick in rear window, Instructions and appropirate hardware to ease installation. We have tested with 4 head up to 10 head light sticks for strength.
