Is there such a thing as performing Electrical diagnostic? There must be a solution for persistent electrical problems, I've summarized below in reverse chron:

In mid-Nov. 2010: headlights, running (day) lights, tail/brake lights are not working, even though mechanic "checked all lights and were all working at this time now". They were not working a couple of days before I dropped off the car on Dec. 14, and now they are not working.

Oct. 19, 2010: same mechanic had checked left brake/tail lights not working correctly, found poor ground connection to that bulb; replaced the bulb and installed new round wire.

May 13, 2010: same mechanic checked lighting, bad L tail/brake light bulb and replaced.

July 2, 2009: same mechanic Right headlight found defective, removed bulb housings and replaced both original headlight bulbs with new.

Can these persistent electrical problems be resolved? I had bought the car in Aug 2004, with about 300 miles, and is currently around 52K.

Thank you for your response.

You can do a certain amount of testing, but this is a manual check and not with a scanner, if globes are blowing often, this can be an over charging problem at the alternator, if the globe holders are rusty and making a bad contact this can affect the earth which can affect other lights as well, if your mechanic is not up to testing all electrical systems, may be you should find a auto electrician, they are specialised in this work.
