I have a 2006 RL. The headlights have always shone white - it's something I really liked about the car when I bought it. Recently the passenger side headlight when out and was replaced at the dealership. It shines yellow and does not match the driver's side. Sure, I could replace the driver's side, but I don't want yellow headlights. My son says the kelvin rating is too low. This has caused a one month (I am not kidding) research process by the dealership. No one seems to know the original kelvin rating and says they just use what is sent. They even went to O'Reilly's Auto Parts and got bulbs. They all shine yellow. Can anyone tell me how to stay with white lights and where to find them?
