Known issue, have seen people opening headlights (bake in an oven) and replacing the reflectors only.
Can get a pair of very nice OSRAM HID bulbs for $100 or so shipped off ebay. Local prices are a rip-off.
@1randomkiwi might want to comment on this
Also, I'd rather go aftermarket and get CrystalEye headlights - auto levelling HID, new reflectors, LED goodness, plug'n'play.
Probably about the same price as what you paid for your manual halogens too.
