How do you change burned out headlights on a 1991 Honda Accord?

A large (appr. 2 inch) plastic ring holds each bulb in place. There is little room to get your hands in there, and the retainers tend to get gummed up and dificult to turn.

If you can get a large set of groove-joint pliers in there, that will help. Turn about 1/4 turn (there should be arrows indicating direction). Pull out of the headlight housing and replace with new bulb. You may find it easier to just remove the battery or power steering reservoir first.
