The Litronics have Halogen high beams which work fine in that capacity. If you have the harness and module, then the low beam tilts up 1.5 degrees to assist the existing halogen high beam. While I have never seen it, I bet it is awesome
There is a Porsche TSB that shows how to add the high beam module/wiring for cars that have had Litronics added, that would be the one I would follow (although it is kind of complex). There are also some write-ups on the web, and also the pelican parts guide.
I can't find the TSB anywhere right now but it is on renntech.org (can't access from work computer) but I think you have to be a contributor.
Set up a search on eBay for the wiring harness and the module; they popup from time to time and sometimes deals can be found...
