Is the Osram Xenarc D2S 66240 worth it?

Yes if your car has factory D2S xenon and one bulb has failed. It is an OEM-grade Osram bulb at $31.99 at eBay as of November 5, 2026, far below dealer prices for the same part.

Will this fit my car?

It fits any headlight that takes a D2S bulb with a P32d-2 connector, common on Audi, BMW and Mercedes-Benz xenon setups. Check your owner's manual or the old bulb's marking before ordering.

Should I replace both bulbs at once?

Yes. Xenon bulbs dim with age, so a new bulb next to an old one can look mismatched in color and brightness. The pack contains one bulb, so order two for a pair.

What color temperature is it?

About 4300K, a neutral white close to daylight. That is the factory xenon color, not the blue 6000K+ look of some aftermarket bulbs.

Does it work in a halogen headlight?

No. It needs a D2S xenon housing with a working ballast and igniter. Do not put it in a halogen reflector.
