I know this question is gonna be an eye-roller for a lot of you, but when it
comes to things mechanical, I'm pretty brain-dead.  So I noticed that one of
my headlights is out on my '88, and went to the FLAPS to get a new one.
There I was told that instead of needing the entire square headlight, I
needed only the filament ( the box says "halogen lamp" and it looks like a
large spark plug with a light bulb on the end of it).  I was told that the
old filament is to be removed, and the new one installed, with the actual
headlight housing never having to be removed.

I'm not sure I was given correct information, and having bought the car
without the owner's manual, I can't get any info on the procedure for
changing the light out. So:

In an '88, is it true that you replace only the filament, and not the entire
headlight?

Is it necessary to remove the grill in order to put a new headlight in, or
how exactly can the headlight be reached for replacement?

Btw, the headlight will light up when I put the brights on, but it goes dark
when only the normal beams are on, if that's pertinent.

Any help appreciated.  I don't want to have to rename Rozinante to
Polyphemus.
