I fabbed these up earlier this evening. Not the prettiest brackets out there but they keep the lights flush and up and out of the way. Simply put, they get the job done and once mounted they are pretty robust. The jury is still out on whether or not I'll have trim them or possibly adjust the bend once the sliders go on, but I think just from eye balling it that they will be fine.
I used a piece of 1/8" by 1.5" flat aluminum stock.
I then marked all of the necessary holes for the bolts and for the wire to run through the mounting bracket when mounted flush.
I used a set of Amazon "Rigid" knock-off rock lights. The location of the wire at the back of the light tended to vary from one to the other. This required a little enlarging of the holes in order to get the wire to sit flush at times.
I reused the existing threaded holes from the factory step supports in order to mount the brackets. I pre-bent the brackets in the vice before mounting the lights and then the brackets to the truck. Once fully supported against the truck you can adjust the bend in the bracket by hand.
I still need to finish wiring them back into the factory puddle light harnesses, hopefully I can get that done this weekend along with the slider install. The aluminum was $11.99 for a 4ft stick and the puddle lights were $20 on Amazon. So for a little more than one pair of Rago Rock Light Brackets I have four LED puddle lights with brackets, I can't complain. I'll post up pics with the finished product once I get them wired in.
