headlights

I was thinking of buying those euro style headlights on ebay for my
car just wondering if anybody here knows the dimensions of the headlights?

What kind of 3series do you have? E30, E36, or E46? I'd order from www.umnitza.com (http://www.umnitza.com) as they seem to have the best quality euro headlights. With eBay you're liable to get a knock off that isnt sealed properly from water.
