ok guys...this is strange I have a b5 s4 with about 93k on it and tonight I notice the driver head light, HID the color turns pink. As for the passenger side, it's still working fine. Can you guys tell me what is going on because I don't have a clue. thanks in advance.

 

prolly the bulb is going. usually the bulbs will fade about the same. if u do get a replacement, get both at the same time

 

Philips told me that they turn from white to yellow before burning out.When my car
had 75K mi. they started changing color. At 112K mi. they became dim, and I
replaced them.

 

thanks guys...I guess this would be a perfect time to up the HID too then...

 

thanks guys...do you know what is the temperature of the stock s4 HIDbulbs?
