2000 996 Litronic Light Bulb Question

[2pbx]

My left OE bulb went out, my local shop said I should change both bulbs. I said change only the one that went out.

He replaces the bad one with an Osram/Sylvania DS2 type (same oem part numbers).

Now when I turn on the lights, the one replaced one looks a little yellow not nearly as white/blue as the OE.

He said they get more blue with age. This doesn't seem right to me, when my car was brand new both lights were bright white.

Has anyone else had this problem?

Should he have used the Phillips bulb?

Could something else be wrong?

Thanks in advance for helping out this Newbie!

It is normal that a new and an old bulb have a different color, change both. The lifespan is approx. 3000 hours for xenon bulbs.
