yes, i used Hella euro headlights on my 190E as well. Very happy on those!!! Over 1 year, still in very good conditon. At least, no leaking.
I know that Depo and TYC are not good quality. If you put Hella or Bosch beside TYC or Depo, the Hella and Bosch are totally different..... Much much best qualities than TYC or Depo.
I sold some Depo euro headlights for Audi A4 before, some of them got leaking problem and the reflector discoloured, but the Hella or Bosch one, never never got complaint.
