I don't have my owners manual handy and I need to replace the upper
bulb in the rear drivers-side lamp cluster (this is the stop/brake
bulb) of my 1999 ML320.
Can anyone tell me what bulb type it is and where I might find it
(i.e. auto parts store, Wal Mart, etc). For some reason P21 comes to
mind but I'm not sure.
Also, how do I get to the bulb in order to replace it? From the
inside, how do I remove the panel, etc.
