My headlight and fog light on the drivers side on my 2011 truck flicker and sometimes will not come on unless I get out and hit it pretty hard with my hand. The other night I was driving and both fog lights as well as the left headlight turned off. I just replaced the bulbs in the headlight but the problem is back. Does this have something to do with a few lights on my dash being on when they aren't supposed to be? My emergency brake light, ABS light, traction control, and a couple more lights are always on. Anyone have an idea what this could be?
