OSRAM XENARC D2R 66250 - 35W Xenon Headlight Bulb with Reflector (P32d-3, 4,100K, 2,800lm)
The OSRAM XENARC D2R 66250 is a high-intensity discharge (HID) headlight bulb with reflectors , renowned for its OEM quality and used as original equipment and replacement parts in millions of vehicles. It delivers a luminous flux of 2,800 lm with a color temperature of approximately 4,100 K , providing a light close to daylight that improves visibility and visual comfort compared to conventional halogen bulbs. With a nominal power of 35 W and a P32d-3 base, it is ECE approved as D2R and requires the use of a specific ballast/starter. Its B3/Tc lifespan of 2,000/3,000 hours and compact dimensions facilitate direct replacement in compatible headlights.

- Fleet maintenance requiring OEM spare parts with certified specifications.
- Replacement in vehicles with D2R compatible HID ballast/starter .
Frequently Asked Questions
-
Are D2R and D2S interchangeable? No. D2R is for reflector headlights; D2S is for projector headlights ( lens ). Always check the category indicated on the headlight.
-
Does it need a ballast? Yes. Every HID xenon lamp requires a compatible ballast/starter that manages ignition and operation at 85V.
-
Can I change just one bulb? It is recommended to change them in pairs to maintain uniform color and intensity on both sides.
-
Does it work for 12V and 24V vehicles? The lamp operates at 85V via the ballast. If the factory-installed HID system is D2R, the corresponding ballast will supply power from either the vehicle's 12V or 24V system.
Installation recommendations
- Disconnect the battery and follow the HV safety procedures of the HID system.
- Do not touch the quartz bulb with your fingers; use clean gloves to avoid residue that shortens its lifespan.
- Check the headlight's references (D2R, P32d-3) and ECE approval before installation.
- After the replacement, check the beam alignment and proper operation.
