It does it make easier. When I did our demo truck I installed the lights onto our bracket first. It is definitely easier that way. Our assembly makes it easy to get things mounted as you can slide the lights out of the way to make room for the mounting holes.
The Rigid 360s are REALLY tight and IMO don't look right. They are so large that they are basically touching each other the whole time in order to get the light through the hole. And even still, some of the light gets blocked by the bumper opening.
You'd be better off with Baja Designs Squadrons or Rigid D-Series lights for the best performance. A round light in the fogs isn't exactly the right setup. Although POSSIBLE it doesn't look right. That's just my opinion though. We could definitely sell you on the 360 lights and our fog kit but I'd much prefer to sell you a good solution then make a quick buck.
You can see how that inner light gets blocked a lot and the lights are just really crammed in there. It'll make it difficult to aim them up/down/left/right as you'll keep hitting the bumper. They'll fit with our CrystaLux brackets which give you a bit more flexibility in how you adjust them. But still.. REALLY cramped.
With that said we DO offer a 360-Series Triple Fog Light Package here:
