Hi Scotty - Have a 2011 Acura TSX 2.4 auto, 80k miles.  The right side HID headlight has turned pink in colour.  It first lights up normal, then fades to a pink colour a few seconds later.  Now, the light shuts off completely a minute or so after it turns pink.  Is this a bulb problem or a ballast issue?  I can probably DIY fix the bulb, but think the ballast requires a pro due to the bumper removal.

An Amazon seller says OSRAM is factory bulb.  I want to match OEM, but so many choices and brands that seem to range in kelvin ratings from "blue" "yellow" or "pink"-ish hue to the light. Just prefer the factory light which is a clear white, and hope to match the OEM left side that is still working.

You and your community are the best!  Thanks so much.
