I had some of those prism "disco-ball" housings on my chev, -they were terrible. I'm running the Hella H-4 housings on my XJ and really like the way the light is reflected. They are kind of between a spot and a flood, -just right. While the Hella housings aren't cheap, they are in my opinion one of the best investments I made.
As far as H-4 bulbs are concerned, -strictly preference. I've used the 1st gen silverstars, and they were ok. But I had an old set of PIIA extreme whites from years gone by, -and they are the ones I'm using in the XJ right now. I don't plan on ever forking out the big bucks for the PIIA bulbs ever again, -so when they burn out, -I'm trying something else.
BTW, -I couldn't help but notice what's on your hood! What else does a fellow XJ'er need besides tools and money?? (beer and women are also on the list).
