My front side passenger Low Beam light is out. I went to the dealer ship and was told it is definately the bulb and not the invertor or the ignighter. I know the p/n for the bulb is D2R, but they are sold me many colors. I'm not sure if I am supposed to get Diamond White or Light Blue. I looked at my drivers side light and it looks sort of light blueish white. I need to know what color originally comes with the car so I buy the correct one to match what I already have. - thanks
