Reported cause · Original poster
As far as I am aware reasoning for this is due to cutting back on the amount of glare and refracted/reflected light projected towards oncoming drivers above the designed cut off of the projector.

I've previously done the same frosted/fresnel to clear lens swap on other vehicles I've owned and definitely much prefer the look of the clean, crisp cut, and increased output it gives.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I noticed while changing out the bulbs on my 2000 996 that the projectors for the low beam use either a fresnel or frosted lens.
Has anyone gone about swapping this lens out for a clear lens
Does anyone know the diameter and height of the lens in the factory Litronic projector?
I've previously done the same frosted/fresnel to clear lens swap on other vehicles I've owned and definitely much prefer the look of the clean, crisp cut, and increased output it gives.
I attempted to do a search but I can never seem to find anything I am looking for with the search function.
Hi OP,
I've never seen fresnel type glass used on a Porsche much less a 996. I use fresnel type spot lights in the television studio business, but I've never seen such a lens used on a modern car. Could you post a picture?
Many people have swapped out the base "halogen" type headlight enclosures with polyellipsoidal based headlight enclosures. Most of the trouble comes with the litronic systems that have auto balancing and powering issues surrounding Xenon ballasts. But Porsche makes a non-litronic protector style enclosure that many have used to avoid headaches with Litronics systems.
Frensel and "frosted" type lenses are used extensively in the auto industry for projector lenses. As far as I am aware reasoning for this is due to cutting back on the amount of glare and refracted/reflected light projected towards oncoming drivers above the designed cut off of the projector.
Wow, I learn something every day. I didn't know the auto industry had much use for such older lens technology like the Fresnel design especially with it's short focal length capabilities. But it makes sense if glare is an issue to oncoming traffic with other projector designs.
For us in the studio business, it's all about light collimation. The fresnel lens is also lighter weight since the lens thickness is a fraction of normal convex type lenses. Weight and size of a lighting instrument plays an important part in our business.
Or you could just replace and update it with this, plug and play lens upgrade for the 996:

So I tried this between calls today, and yes, you can pull out the projectors out the back of the headlight. It isn't "easy" but it can be done.
