Just got my 13 CS two weeks ago, and now planning on do some work to it to make it look more nice. And I wanted to know how many of you will change the fog light to HID, and how many of you will stay with factory. Just doing some research to see what you guys will prefer.
I will post some photos before it goes in to the body shop, so I'll have before and after photos to share with you guys. Thank you

 

You could consider this Techart front spoiler

 

The answer depends on if your looking for looks or if your looking for function. The purpose of the fog light is to penetrate fog and to do that.. it has to be below your headlights closer to the ground so the light from the fog doesn't bounce directly back at eye level. Next.. it has to be a different color than the fog that's why functional fog lights are typically a yellower shade.

Now a lot of people like the "looks" of it rather than function since they don't have "fog" in their area.. well I live in San Francisco so there's fog haha.. for the purpose of the looks then yes the HID will make it look better but it'll also be more glaring to oncoming traffic.. because just like headlights with the "reflective bowl" design.. it wasn't designed to control the 3 times more light output that HID technology has to offer. The amount of glare varies depending on design.. I'll be picking up my CTT today actually and I'll be able to give you more accurate feedback then.

All factory HID bulbs are made by Philips or Osram and they are at a K* temp of 4300k and will eventually color shift to 5000k after about 100 hours. 4300k is the natural color of sunlight in the afternoon. So keep this in mind if your getting an HID kit even though.. this is coming from someone who hates HID kits to death.. lol..

Great points Larry
IMO,fog is the most treacherous driving environment on the road
Scares me more than anything
So while I do,as much as possible,want to see where I am going...I would NOT want to adversely affect any oncoming traffic ..

 

Thanks Larry, I am also in San Francisco, but I don't drive it out when there's fog or rain, so it doesn't matter to me if the fog light is not helpful. and my friend had suggest me to change it to yellow, the yellow that fog light use, but I don't think that fit on a SUV since the fog light that cayenne has is not that big... So after few days of thinking, I'll go with HID I just want it to look good and not use it for fog. thanks

 

pepper09tt, that's a nice body kit, I'll search some photos to see if it will look nice on a white CS. thanks

 

Actually HID kits do go down to the 3000k range which is the yellow color so.. HID and Halogen bulbs have different "base" which is the fitment on any headlight or fog light assembly, it has nothing to do with how big or small the visual appearance of the fog it nor does it have anything to do with it being an SUV.

I haven't taken a look at the fog light so I don't know which base it uses (H7, H11, H1.. etc). I will caution against using an HID kit in there since it is a reflector type fog light and not an projector type like your headlights so there will be excessive glare that is annoying and potentially dangerous to oncoming drivers. To compromise, if your just going purely for looks, it is cheaper and easier to get like the Silverstars halogen tinted bulbs which will match your factory HID low beam projectors, not blind oncoming driver and give you that "look" if that's what your going for.

For me since I was and still am in the lighting technology industry.. I plan to redesign the headlights and then retrofit HID projectors into the factory fog lights to get the proper brighter lighting without blinding oncoming drivers ..

MaLau if you need assistant in getting the right bulbs and getting it installed just let me know since I picked up my CTT a few days ago and can take a look at mines and tell you.

I'm also considering the TechArt spoiler and I have a white car, I swear I saw a picture of TechArt with a white spoiler on it from their website or pdf file or something.. I just gotta find it..
