Hi-
I've been running the square H4 e-code headlights for 10 years or more (w/100 watt hi beam bulbs, and a full complement of 10 gauge wiring and relays).  The passenger side large lamp is losing it's reflective coating presumably from moisture damage.  What remains is tarnishing or corroding or something causing the output to slowly fade away.  The driver side lamp is fine.  With a full set of new lamps going for $425+, I'd like to know if any listess know a source willing to break up a set and sell one lamp.

Since these were stock lights in Europe and should be considered a "keep it stock crash part", I'm wondering if I'd have any luck trying to find it over there.  Anyone know of a source that might do this for me?
