First gen. I would post the thumbnail link, but they always screw up lately for me. Google FXR output pics for what the output looks like.

 

Holy bawls, fitting FX-Rs into anything 2nd gen would be almost impossible. I would go with Mini H1s from theretrofitsource.com for anything smaller than the 7x6 housings. The current version of the Mini D2S isn't bad either, but the H1 is better if you don't plan on using OEM bulbs and balasts.

 

I could fit FXR's in the trailblazer but I am not sure if I want to spend FXR money haha

 

FXRs aren't much more than the minis really.
