Lights, all of them!
So my car appears to have xenon/ HID's? And standard halogen DRL's / fogs. It seems to me the head lights level is too low, from what I can tell the auto adjustment works? I have no errors but the low beams just seem too low and too close to really be of any use. Can I re-program the light adjustment? I saw a post on here the other day about a 991 direct swap for the fog's and that looks nice, is there any good direct swap head lights? I might want to convert to LED's and this is a rare occasion my googling skills are failing me. Lastly does anyone know of a good place to grab plug and play LED bulb's for the interior lights? I'd like to swap anything I can to LED. Thanks in advance for any help.

Maybe this post is on the wrong forum. 991 Turbos (like 997.2 turbos) don’t have fog lights. Perhaps it should be on the regular 997 board?

Is it? I have a 997.1 TT...I'm trying to figure out how to fix the headlights aiming low and replace the interior bulbs with LEDs...

One reference I can find about headlights is the dipping/leveling that occurs when you first turn the ignition key with the low beams on.
Another refers to adjusting them vertically. Check you manual and see if it is there. There was some discussion on whether this would work for the self leveling lights, but it seems it will work for them as well, although I have not done this myself. From one of the posts:
" To adjust the lights if you still have issues:
You'll need a long reach 5mm Allen key to adjust height (at least 150mm long).
Open the bonnet, remove the carpet / trims adjacent to lights and the adjusters are under the rubber covers (one above the other) the big round bung covers the mechanism to remove the lamp unit (leave that one alone!!)
To adjust the height, turn the lower adjuster only - the upper adjuster is for lateral adjustment
Mark the original height on a garage wall (for example) and providing the car is parked in the same spot each time you can make adjustments knowing where to go back to if necessary. "
I am happy with my lights, so i would think you should be able to improve yours.

Partially yes, I just happened to see that and was curious if there were any headlight swap options for LED's

I know that there are some 991-style aftermarket headlights out there for the 997. I believe that they utilize the existing HID lamps and hardware, and it’s more of a cosmetic modification. Have you installed new HID bulbs in your OE headlight assemblies? This may make a difference. HID bulbs lose intensity as they age, and the color temperature changes. I think the lifespan of HID bulbs is generally around 10 years, depending on use. You also have the option to change the color temperature if you change bulbs. The OE bulbs are 4,300K. Many aftermarket bulbs offer a whiter light, with temperature of 5,000K or more. Anything over that results in a blue light, even moving towards purple as color temperature increases. You’d obviously want to avoid those.

If the leveler is not working you will want to get that addressed at some point.

Coming from a Honda S2000 platform which has one of the best projectors... I was very disappointed with Porsche's HID performance. I had a spare set of cheaper but more reputable bulbs, so instead of installing them in my Honda I said well what the hell since Porsche's light output is inferior at least I can have updated headlight color. Long story longer it turned out that my Philips bulbs were just tired and color output aside the distance and brightness (Lumen & Lux) was drastically improved. My 911 output seems to be almost as good as S2000's even though 997 uses frosted lenses vs clear on S2000 projectors.
Here is where you can buy these XB35 5500 Kelvin D2S bulbs:

Here's my Instagram post:
Also, in your frunk there should be a tool that you can use to adjust the height of our lights if auto-leveling is off a little.

Funny...I was doing a ton of research this weekend as I noticed my bulbs seem tired. They are the original bulbs and given that I have the DRL feature enabled, I'm sure there's a significant amount of hours on them. A lot of new cars seem to be using higher Kelvin bulbs to give off that fashionable blue or purple light. I watched a bunch of their review videos and I think I'm going to go with the Osram bulb.
I do remember there was a guy that upgraded the lenses on the headlights and it made a decent improvement...can't find the thread now but I think it was on 6speed.
