OSRAM 66340 XENARC ORIGINAL D3S Xenon HID Bulb
Headlights slowly turning pink, flickering, or one side noticeably dimmer than the other? Xenon bulbs age gradually — light output drops and color shifts long before the bulb fails completely.
The OSRAM XENARC ORIGINAL D3S (part 66340) is the OE-quality replacement: the same bulb line OSRAM supplies for new-vehicle assembly. D3-generation bulbs are mercury-free, have the igniter integrated in the base, and work only with a D3-compatible electronic ballast.
Part Numbers
- 66340 (OSRAM XENARC ORIGINAL D3S)

When to Replace — Common Symptoms
- Color shift toward pink or purple
- Noticeably dimmer light output
- Flickering or intermittent start-up
- One headlight visibly different in color than the other
Tip: xenon bulbs are usually replaced in pairs — both age at the same rate, and a fresh bulb next to an old one will look mismatched.

Product Type
Xenon HID headlight bulb (gas discharge), category D3S
Function
Produces the headlight arc inside factory xenon (HID) headlamps. Powered by the vehicle’s D3 electronic ballast; the integrated igniter starts the arc, and the ballast regulates it at 35W.
Compatible Vehicles
Fits any vehicle whose headlamp takes a D3S bulb (common in vehicles from around 2008 onward with factory xenon). Check your owner’s manual or the marking on your current bulb — it must say D3S.
Important: D3S is not interchangeable with D1S/D2S/D4S. If your current bulb is not a D3S, this bulb will not work in your headlamp.

FAQ
Will this fit my car?
If your vehicle uses a D3S xenon bulb — yes. Check the owner’s manual or the marking on the current bulb; it must say D3S.
Is this the same bulb my car came with?
XENARC ORIGINAL is OSRAM’s OE line — the same bulb family supplied for new-vehicle assembly.
What color is the light?
Approximately 4300K — the standard factory white of OE xenon headlights (not a blue tuning bulb).
Should I replace both bulbs?
Recommended: bulbs age together, and a new bulb next to an old one will differ in color and brightness.
How many bulbs are in the package?
One. Order quantity 2 for a pair.
