Headlights Turn Off While Driving problems of the 2008 BMW 528

Driver side headlight went out, so I automatically assumed that the bull was blown. Went and bought $100 bull that controls the high beam and the low beams, replace the bulb, and the headlight still doesn't work. Took the ball back and got another bulb, and the headlight still doesn't work. As I was replacing the bulb I noticed bare wires showing, on multiple wires, as far as I could see. This is definitely a safety issue , as it could cause my car to catch fire.
