I tried LED's on both headlights and fogs but to be honest they weren't as bright as i was hoping. I converted to 55w HID's and I wanna say they're at least 5x brighter than the Cree LED bulbs I used. Now i understand you're talking about an entire swap including the housing but keeping your originals obviously will have the best fitment and beam aim, also just restoring the lens on them will save you a lot of headaches and $$$ and you can entertain the options of swapping bulbs for LED's or HID's.... Options are endless
And since your screen name starts out JDM id recommend some bluish headlights 6000k or 8000k and 3000k fogs for a JDM theme look.
