as the title says I'm trying to change the bulb in the right front marker light on a 1986 Honda Accord. When the headlights are in the up position I can see the bulb mounting assembly, but there's no room to get in there to change it.

What's the trick? The lenses are mounted in such a way that I can't see any external screws and the Haynes manual is useless.

 

In the bumper below the light there is a "plastic" piece/window/insert.....pull it out...can't remember if it is top first or bottom first......once out you'll see the screw that needs to be removed, then the lens will slide out.
