I found something else on eBay that looked interesting:
http://cgi.ebay.com/ebaymotors/ws/eB...#ht_4689wt_975
It's a complete kit, housings, bulbs, ballasts and harnesses, for ~ $100. And it says they are projector housings, which should mean they will spread the light correctly. The only thing I'm wondering is, do these have proper high/low beam function? It says H4 hi/low bulbs, but I want to know that both will work properly.
