$24 for the pair at the local pick-n-pull. I brought the whole headlight assemblies up to the counter and they wanted to charge me $90 for "HID headlights;" I told them I only just needed the housings and they let me disassemble them there and knocked down the price (considerably).
Unfortunately one is missing the black plastic retaining ring for the bulb:
I looked EVERYWHRE on the lot for one, checked a dozen other BMWs of similar vintage: Nothing. Sigh.
Besides that, for you xenon retrofit folks, what else do I need? Bulbs, ballasts, wiring pigtails, and......? I assume I can code out any light-out warnings with PASoft (which I have yet to get up and running)?
Still not sure if I'll use the black headlight shrouds. My car has the silver ones and I like the contrast with the dark paint. If I do go with the black shrouds, I need to get some turn signals with the dark housings also...
