Do you already have the bar, cause you need to make sure you have enough space in the middle because mine has l think 22" in the middle and with the mounting brackets my 20" light becomes 21.5" so you need to make sure you have room for everything before you order it. I got my light off of Amazon for $90, can't afford a $500 rigid light with a daughter driving, but it worked the first day and continues to work and puts off a pretty good amount of light. I would recommend buying a wiring harness, I got one on Amazon for $35 shipped, it's from rigid industries and it has the relay and power and ground hookups and even a switch all I had to do was clip the end off because it comes with a plug for a rigid light and splice mine in.
