[W126 Coupe] Passenger headlight bulb only glowing at half strength

[Richard Hesek]

 I have not had just one head lamp do this but when my alternator started 
to fail and did not adequately charge the battery both headlamps went dim.
 Along with that, my seatbelt presenters started cycling during driving 
and my hazard flasher started.
You might want to test your battery and alternator.
