I wanted to mount 2 round lights on my grill, but didn’t want to buy the prospeed light bracket or use the OEM thru the bumper kit. So I used a 1 1/4” square stainless steel bar and 2 Harbor Freight ATV Winch Mount Brackets and some stainless steel fasteners . I have a total of around $35-40 in parts ($20 bar, $10 brackets, $5-10 fasteners). I’ll find out if I need additional support after I use for the next little bit to reduce bounce. Sort of upper support like the prospeed. If so I’ll need another $15-20 in stainless square bar. The winch mounts have multiple holes so it would work with pretty much any light you want, round, square, or bar. There’s about a 3-3.5” working depth. Here’s some pics. Not as clean as the prospeed, but more flexible and cheaper for my purposes.
