4300k would be closest. There's 3500k but they are super yellow light the usually get put in fog lights. Not necessarily on our trucks but have seen them in WRX's and some other cars.

Check into retrofitting since it hasn't been mentioned yet. Theres good info on the board for it. Or theres the eBay projector lights for a couple hundred bucks, unfortunately a lot more than just bulbs and they aren't very good lights. Have heard they get melting and condensation on the inside. Still safer for the hid's to be in, for others.

Is what it is though.
