Litronic Bulb Question

[GWPORSCHE]

After an incident, my right side factory-equipped litronic light was replaced. The problem is the new passenger side and driver side low beam color does not match. The old light is closer to white with a slight green tint to it while the older driver side light is much more purple. The car is a MY2000 w/ 76M Miles.

Here are some other facts:

1) Both lights turned on for the first time after being off for a few hours starts of the same purplish color with the newer light turning to a lighter color within minutes, while the older light stayed relatively purple.

2) Both light output seems the same

3) Pulled the bulbs out and discovered that they have different part numbers on them:

Left Bulb (older):

Philips Germany D2S 35W E 85123 e1 03V 9MO1

Right Bulb (newer)

Philips Germany D2S 35W 85122 e1 03V M407

Can someone please tell me the if the difference in color is just due to the difference in the age of the lights or is it because of the different part# found on the bulbs? Thank you.

Quick question. WHen your comparing them are you doing so with the car running or off in the driveway just turning on the lights?

Many of my previous cars had one light that looked different from the other when I turned them on while the car was not running. Because it take a 30 amp shot initially to turn them on then they run a 5ams afterwards, if the car was not running one light would look fine, the other looked dimmer and wierd.

I started up the car and turned the lights on again and they were the same. I guess they needed the power of the alternator running to have them ignite the same for whatever reason.

If the car was running then it definately could be age, or your old bulb is about to burn out. Ever seen guys with HId's and one is normal looking and the other is almost pink looking? (see this all the time in Mercedes Benz now cause they are gettin older and have HID for a long time) its because the bulb is shot and the guy hasn't change it yet... It could also be a sign your bulb is on the way out.
