I have a '97 528i. One of my headlights wobbles excessively. My dealer told me this is a common problem which can only be fixed by replacing the entire headlight assembly. The other headlight is starting to come loose as well. If I replace both with stock units, the bill will be $600. I see 2 possibilities (other than having the dealer do this). 1. find a fellow owner who has replaced his good headlight assemblies with aftermarket unit and buy the old ones from them. or 2) find a good aftermarket alternative. Any advice...or offers to sell. thanks
