if you're talking about the pollyeliptic ones try a local scrappers, i wouldn't use ebay for it as they seem to be a bit high priced on there, also try the classifieds section on here
would ya not just get a h.i.d kit they look deadly i got two kits in my marea one on high one on the low beam look really well and not really over expensive
I've asked a couple of scrap marea owners if they are willing to sell their "polyelliptical" headlights and there is someone on here that is looking to sell theirs in a few weeks so all should be well!
