Description
Genuine OSRAM · Part no. 66450
The OSRAM Xenarc Original 66450 is a D4R xenon (HID) bulb for reflector headlamps, a mercury-free type that plugs into a separate igniter. It is OSRAM's original-quality D4R, ECE R99 approved, in a single box, for cars whose headlamps were built for this bulb.
Good to know
- Can a D4S go in instead? No. The R marks a reflector headlamp bulb and the S a projector one; fitting the wrong letter gives a badly shaped beam.
- How do I tell D4R from D2R? D4 bulbs are mercury-free and run at 42V, D2 bulbs at 85V, so they are not interchangeable; read the marking on the old bulb.
- Is it safe to change at home? Lights off and the lamp cool first, because of the high-voltage igniter; if the headlamp has to come out to reach the bulb, follow the handbook.
Which one?
For projector headlamps, the matching bulb is the D4S: see the OSRAM Xenarc Original D4S (66440) or the NAPA D4S Headlight Bulb (NBU142402).
