Left fog light coming on/off

[Evil Empire]

My front left fog light goes off randomly while driving and doesn't want to turn on for a few days after it goes off. A few days go by, it turns on perfectly...and then randomly turns off while driving again. The right fog light is fine 100% of the time. The fuse is fine, the bulb is fine (I've tried 2 other pairs, it did the same thing), and all the wiring seems to be nice and in order. Any thoughts?
