When converting the W124 model into the later W124 E-class with the changed bonnet (with that integrated grill), we only need to exchange the head-light lenses. The light unit itself is similar to the older/newer head-light units.
The only difference is that changed upper corner of the lens along that integrated grill-trim of the bonnet.
Lenses on european euro lights are interchangeable.
Just wondering...what are driving lights (on the 500 head lights); is that something like the beamers in the bumpers of most of the AMG models?
