headlight bulb replacement
 

hello i have a 1991 300d 2.5, how do you replace the headlight bulb, i got as far as removing the electrical harness, but can not get the bulb out, do you take it from the back or do you take the whole assembly out from the front? any help would be great,,,,

Remove it from the back.
