My Driver's side brake light works.. then doesnt work.. then works again and doesnt work again lol.. its completelly random, its not the bulb.. cuz it just doesnt work randomlly.. but anyone have any idea what it could be..?

 

Check the wiring harness(es) and plug(s) to see if they are loose or if there is a short.

Also, check inside any plugs to see if the metal connections are corroded. This happened to my wife's Accord.
