The Euro lights that seem to be available are:
1) Used MB Euro lights with vacuum leveler and star stamped on them, made by Hella or Bosch for MB. Mine were $300.
2) Hella or Bosch Euro lights for that model MB, but not provided to MB or stamped with star, may or may not have vacuum actuator. $ = whatever the market will bear.
3) TYC or Italian Aftermarket Euro lights.
The Euro lights use an H3 fog lamp bulb. I don't know if the yellow reflector from your old US lights will work in the Euros, I solved the problem by ordering Hella H3 #78136Y, which to oncoming drivers makes the fog lens appear white with a slight irradesence, but from inside the car throws a traditional yellow fog pattern.
I think there is a discussion of TYC and Italian euro lights in the archives from about a year ago.
