DISCUSSION:
When an HID (Xenon/High Intensity discharge) headlamp bulb is replaced, there may be a visible color difference between the new lamp and the one
that has been in the vehicle for some time.
An HID headlamp has a very bluish/white light spectrum. A new HID bulb will tend to have a color temperature at approximately 4150K, an HID bulb
with operational time and age will shift color temperature towards a slightly higher value of approximately 4300K. If you have an existing HID headlamp
on one side of the vehicle and a replacement HID headlamp on the other side of the vehicle, the headlamp with the new bulb will appear more
yellowish/white, while the headlamp with the existing bulb will appear more bluish/white when on. Due to the physical properties of HID headlamp, the
color of the bulb will change within the first 200 hours of operation about 150 - 200K (color shift). Once this breaking-in period has passed, the color
appearance becomes more bluish/white and resembles the original bulb, so that the perceived color difference is small.
Do not replace a working headlamp bulbs for this condition and advised the customer that this is a normal occurrence and the color will change.
