One of my headlights has been dim for a few months. Then both went out completely so I just had the headlight bulbs replaced a month ago. The driver's side headlight went back to be dim in about a week. Now they are both out again. Does this sound like a wiring problem? Is this expensive to fix?

You may want to have your alternator checked for its output. Most parts stores will do the service for free. Seems like your alternator either overcharging or too much fluctuation in its output. Advise us the outcome of the alternator test.
