1990 brought the Stainless Steel strips atop the bumper covers and a thin strip along the car's side, at the top of the lower body cladding; this was common to the entire W124 line, from 300D thru 500E (which became available in 1992, along with the 400E)
As to headlights, all E500s ('94 was the first year in the US with the new name; '92-'93 they were called 500E) as well as other '94 E-class models had E-code looking headlights, although they are DOT-spec. Earlier cars had the 2 piece lens setup.
