I just finished up my FX retro this weekend and I love the output of these lights! I wound up using the Orbit shrouds and leaving everything chrome, I like the look a lot. I purchased some of the OEM lights from Amazon for $92 a pair and they worked out great. No night shots yet but everyone already knows what the FX output looks like. I used TRS ballasts and bulbs. I also found a nice weather resistant fuse block. I installed an individual circuit for each ballast. Each ballast has its own fuse, relay, ground, etc (I have four, headlights and fogs). It is very unlikely I will loose all of my lights at once. You might notice my retro fogs too, the Blazers and the FX's both have excellent cut-offs and they just work great together!
