I'm sure you've checked but are the fuses OK? (W124 suffers from fuse-rot resulting in high resistance at the fuse and so low volts to the relays etc).

In the fuse box under the bonnet by the drivers side bonnet hinge. fuses 13 (left) & 14 (right) are the low beam (on mine anyway). The fuse box lid SHOULD have a fuse & relay card listing in it....).

If any of the fuses are corroded I would replace them all - they are a source of loads of gremlins - cheap at Halfords in the little plastic packets..
