2005 s40 HID headlight headlight assembly replacement

[leeursel]

Regarding 2005 s40: can i I install my HID bulbs and ballast into a Halogen assembly to replace a broken HID assembly.

You'd have to swap over the projectors, bulb housing, and wiring harness.

To easily do this, you'd have to disassemble the entire headlight assembly. At that point, most people just buy cheap aftermarket Halogen assemblies and swap over the parts they need to their current bixenon assemblies.
