- If you want to maintain a stock/OEM HID look check out Philips D1S HID bulbs
(assuming you have factory HID headlights). 4300k is what is used in all factory HID equipped vehicles. It's the brightest, most functional and will not have any blue color to it.
If you are running an aftermarket HID kit
in your halogen headlights/fogs then you need 9006 for the low beams and H10 for the fogs. Stick with 4300k.
