94/95 124 chassis had a Factory TSB on headlamp lens mount modification.
These were Benz first DOT Euro style H4 for 124 chassis and guys were popping the lens off [ they just snap clip into the housings] and putting in the Euro lens only.
DOT jumped in, so US dealers got the TSB from Benz to glue the lens snap clip mounts so they could no longer be serviced or be swapped..
So, you may want to see if yours did not see the TSB...most didn't, but some did.
I swapped out to Euro lens, but the DOT/US are just about as good ..the crap ones were 124 chassis pre face-lift 94/95...
Got mine at Capitol...............
I have the original set of DOT , but they are road rashed out enough that they are no longer inspection passable and I would not sell them [ or even give them away] for that reason.
