I put a set on my 96. They were too cool watching those arcs strike on the table at Carlise. High beam/Low beam moves a shield to block or uncover a reflector, the arc doesn't change (of course like dual filaments)! I picked the light blue range, purple was just too much! I got them with extended wiring and the small ballasts. In the end I mounted the ballasts and most of the wiring inside the head light bucket attaching the ballasts to the sides and tie wrapping the wiring out of the way.
Given the bigger draw, I decided to run the power and ground out to separate connections, independent of the OEM circuits. The problem was getting the wires out through the center of the pivot like the OE wiring. Turns out GM choked the hole and I had to remove the whole thing and to grind the hole full size to get the additional wires out. The only plus was the nylons were dirty and needed lub. They wouldn't have lasted and the motors were being unnecessarily loaded, (not good given their fragile nature.) I already had an accessory fuse block added and created a new ground point.
Everything works great. But I used the same light housings that I had already changed to the Euro style, ie lamps insert from the back. I have yet to change to the special housing with the focusing lens. Lots of light at night particularly on high beam, as advertised, there is light way beyond anything else. Mine might be a tad high because I got flashed a couple of time not that I see much night driving anyway. I don't have any pictures at the moment but I need to take some next time the covers come off. Good luck
