Bi-xenon Retrofit for 987s?
 

I couldn't find a thread on this already so here goes. I know you can put the Litronics in a 986. Is there a similar option for 987s? I'm looking at an 05 without them but would consider upgrading if it's doable and not crazy expensive.

You may be able to price the parts at Suncoast Porsche.
I was looking at a good deal on an 04 S without Litronics and, if I remember correctly, the parts to convert were almost three grand, including some really expensive and difficult to change wiring harnesses. I opted out on the deal.
987 light stuff looks to be a little less complex than the 986, so it may not be as bad.
