Despite new headlamp assy's with Silverstar bulbs I found that my SHO headlights were still noticeable less bright than the stock halogens on our new Saab. Well, problem solved. All it took was a modest investment, a few nights at the workbench, and about 75 different hand tools.
The result is a '97 SHO with fully functional bi-xenon projector beam headlights: (pics attached).
Needless to say, visibility is infinitely improved. When I get around to figuring out why my digital cam keeps telling me it's "full" when I know it's not I'll post some night shots.

Michael did you also do a harness upgrade ? I like the xenon but the harness/silverstar set up is quite good . You must be able to see in xray vision now though !
I built my own 10/12 ga. harness and relay setup for the ballasts and I plugged the hi-beam solenoids directly into the stock headlamp harnesses. The only mod needed was a 3A diode in each to prevent arcing at the multi-function switch.
I was pretty happy with the SilverStars until I drove the Saab, that's when I committed to the upgrade. Night & day difference with the bi-xenons, if you'll pardon the pun.
After looking daytime shots are killer looking. Where did you find these at and how long?
I picked up Audi projectors and ballasts on eBay, then built adapter plates to mount them to the stock SHO headlight gimbal so they're adjustable.
Total fab & install time was ~16 hours over 4 days, though with what I learned in the process I could probably knock 10 hours off that next time around.
Mike has promised a full write up on his killer light project.
