The euro's are definitely worth it - best money I've ever spent on my car, IMO. The one-piece glass european lights make my '85 300D look like a whole new car, and the lighting performance is much better than what I was getting from the original sealed beams.

As speedy300Dturbo said, The Hella/Cibie/IPF H4 7" sealed-beam replacements are a cheaper alternatives to the real european mercedes-benz headlight assemblies. You will get a good e-code beam pattern and good lighting performance, but your car's outside appearance will remain unchanged.
