Turned off the headlights for a moment, turned them back on and it was the white color at first but after about 10 seconds began dimming.
Leading evidence: 'white color at' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'white color at' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check with them first' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Yes I'm a PCA member and the parts and service guys at the local dealer know me so I'll check with them first before ordering online.

Suggestion
HID bulbs (I'm assuming you have Litronics) should be replaced in pairs because the color and light output of an HID bulb changes significantly over it's useful life.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Noticed this morning that one of my headlights is turning a little more purple in color than the usual white.
Turned off the headlights for a moment, turned them back on and it was the white color at first but after about 10 seconds began dimming.
Is this a sign that I need a new bulb? If so what is the best source for one?
Generally color changes or flickering are signs that a bulb is about to go.
HID bulbs (I'm assuming you have Litronics) should be replaced in pairs because the color and light output of an HID bulb changes significantly over it's useful life.
I bought my last set from Pelican Parts.
Second what Dennis said. Any change in a bulb's output or behavior is almsot always a sign the bulb is about to go out. (Once though in the case of my Boxster it was a headlight assembly loose, but along with the headlight all bulbs in that assembly were dark.)
For any bulb I replace in pairs.
I've bought replacement bulbs from the local Porsche dealer parts counter but there are of course online sources of parts as well.
Sincerely,
Macster.
Thanks guys!
I found them on Pelican for about $70 a piece, does that sound reasonable? I'll also call the dealer and see what they have for a price as well. Might just be easier to head down the street to pick them up.
My dealer's parts department gives me discounts on parts arising from my PCA club membership. Be sure you mention you're a PCA club member.
If you're not... I would recommend you become a member.
Sincerely,
Macster.
Just buy them on eBay - there's a company that harvests them from wrecked cars, tests, and resells them - for like $10 a bulb. I've bought several sets this way.
Well it went out today so I had to go to the local auto parts store and pick up a set.
I tried the dealer first but they didn't have them in stock so they just suggested going to any parts store. I did and was able to pick them up for around $80 a piece. Sure it's more expensive but with the weather we've had here I really can't be driving around with one headlight for too long.
This is a source reference. Confirm exact model applicability in the original material.
