Leading evidence: 'Use 85 watt bulbs' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'higher watt bulb than should have been used' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Clean inside' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

The yellowing is on the inside of the lens, this was caused by a higher watt bulb than should have been used.

Have you guys seen if it's possible to take apart the headlight to clean the inside and then seal it back up?

Can I replace just the lens cover inside the headlight?
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 just bought a 996 and noticed the headlights have yellow spots inside on the lens. The previous owner used 85 watt bulbs. Can I replace just the lens cover inside the headlight?
Thanks for any help.
I had the same issue. If yours is pre-2002, I'd suggest getting the Litronic kit for it. For the early 996s, the kit isn't really stupid money. I think I paid around $2400 Canadian installed. It really freshens the look of the car up, and the lights are better. To your question, I was told there was no cheap and easy fix for the 'burn in'. It's common in Canada because of our daytime running light law. Porsche doesn't add a low wattage secondary lamp to meet the requirement. They just have the cars run with the headlights on all the time.
Have you guys seen if it's possible to take apart the headlight to clean the inside and then seal it back up? It was something the MKIV Supra community has done when they get yellowish/cloudy lenses. Might be worth looking into versus spending a grand on new lights...
I have taken a spare headlight apart. Had to destroy it to do so.
The reflector and lense in front of the bulb are plastic, not glass or metal. If you have a burn spot I do not know of any way to fix it. Live with it or replace the headlight.
are you sure the yellowing is on the inside? yellowing of lens on the EXTERIOR seems to be a common problem as cars age and the elements they are exposed to can cause it.
im now in the process of removing a scratch/scuff on my lens using this product:

consider it dermabrasion for the lens. you strip away the cruddy layer is what youre doing with this.
while i had no yellowing, i am happy to report that im very pleased with the results so far. scuff was pretty deep and opaque. looks much much better... 10x better. nearly invisible now. i keep working on it to get it perfect. this prodct may be worth a shot.
Thanks for all the replies. The yellowing is on the inside of the lens, this was caused by a higher watt bulb than should have been used. I have a 2000 996 and there is now yellow turn indicator on the lens. Is this a aftermarket headlight.
