997.1 Halogen to Bi-Xenon conversion?

Hmmm,.. not until now. Thanks for the info.
3,200 might be nice,.. or even 3,400 or 3,800.
Most lighting types that aren't incandescent or Halogen produce a horrible light spectrum. (LED and CFL for instance) where the spread looks like 3-4 large spikes,.. with nothing in-between. You can't rectify that by changing to a different "average" color temp.
Even though the mean color temp may be 3,000k or whatever,.. that might in actuality consist of a high, thin spike at 7,000k,.. and a gentle hump at 2,200k,.... and nothing in-between.
LED is a technology that simply isn't ready for prime time. Perhaps given another 30 years?
But Xenon produces a very even-spectrum light,.. so simply changing bulbs (and adjusting the lights up a tad) may get me to where the car can safely be driven at speed at night.
These cars are so effortlessly fast,.. that great lighting is paramount.

I just did a search on Phillips' site,.. and they only offer the D1S type bulb in the 4,200k color.
They produce other Xenon bulbs,.. (D2R, D4, etc,.. but they are also all 4,200k.
You have to be VERY careful when swapping out bulb types,.. as any change in the length and positioning of the light source can have catastrophic effects on the beam projection.
Most of their light-bulb types are a touch fatter, and don't project out nearly as far from the base as the D1S.

I did a little searching for D1S bulbs and I found some other color temperatures. VisionPro offers a 3,000K bulb. That may be a bit too yellow for you, but it you're looking to maximize visibility (especially in poor weather conditions) then it may not.
I haven't had any luck finding a 3,400K D1S bulb. Maybe there's one out there somewhere....

The reason is better visibility. Blue and white lights look cool, but they suck for visibility.

If you're talking about converting 997.1 headlights to 997.2 headlights, I'm pretty sure no one has ever done this with the self-leveling and DCL working. There have been threads about this in the 997 turbo forum, and I've done the swap myself. The lights work, nothing else. Have you tried?
It is possible but a lot of work is required. What you need is a really good mechanic who is well versed in electrical engineering. It is not a simple plug & play job.
You will only need to purchase the bi-xenon assembly. However, you do not need the ballast as it is swappable (if your 997.1 car has ballast already). Your mechanic needs to make a new pin-out (the new assembly uses 3-pin while the 997.1 uses 2-pin). In addition, you will just need to transfer your 997.1 light leveling mechanism to the new headlight assembly or else you will get error code. This is all the easy part. This step will get your 997.2 headlight to work just like your 997.1.
The hard part is getting the Dynamic Concerning Lights ("DCL") to work. You will need to purchase the new 997.2 front wiring harness and also the DCL control module to work. If your mechanic has time, he can come up with a wiring harness pin by looking at the DCL control module. After which, you will need to do the coding to tell the car you have DCL function.
So all in all its quite a big job. Easily a $3.5K job excluding labor charges.
Good luck with the project..!
