I have a 09 997.2 C4S Cab, I’m not too sure which lights I have but they’re stock. Are there any simple
bulb upgrade to go fro the crappy halogen/yellow ones I have to something better?

TIA

 

Thought about something like this for our 2009 Cayenne. Our 997 has xenon headlights. I did replace our 997 Fog lamps with LED from same company, works well.

Replace Bi-Xenon with LED - Rennlist - Porsche Discussion Forums

 

After a lot of feedback and amongst the options (including led conversions etc) , I just went with these and very happy vs OEMS

So you have halogen, and dont have the bixenon option headilghts?

 

Honestly, I dont know which lights I have or the different models for this car...trying to figure that out

 

Look at your cars owners manual, Google it, search the forums using Google by placing “rennlist” in your search.

This has been discussed dozens if not hundreds of times.

 

Look on your options sheet, or call your dealer and have him look it up. You need to know if you have bixenon. If you do, you already have a ballast for the bixenon bulbs. Then you can change the bulb to a different or brighter bulb. It will make a little difference.
If you have halogen, then you buy a conversion kit with a ballast in it and convert to the brighter bixenon. Then you will see a bigger difference.
And you can match the side markers to the headlite and the already led running lites. They will all match better.
