umnitza headlights arent truly plug and play but they do sell an adaptor kit for something like 25 bucks that will make it plug and play. if you want to upgrade, go with a set of "euro smiley" headlights. increased light output incredibly as opposed to your stock ellipsoids, and definitely not as expensive. if you want to go with even more light, you can put an H.I.D. kit in your low beams, preferrably 4300K or 6000K.
eyes for our e34, although final decision is based upon owner's taste, sort of don't "flow" with the car.
