why's headlight out?

Tonight i left my car running outside to get something in the house real quick and when i came out and got in my car and thought something was wrong with my headlights. Long story short, my left headlight is out, but the corner light is not. It does come on when i put my high beams on. So i don't want to go riding around with only one headlight on or riding around with both on high beams. I didn't have the time to swap the bulbs and check fuses tonight, i plan on doing all that tomorrow, but any of you have any tips on where i should start?

The bulb has two parts, one for low beam and one for high. Sounds like you blew the low beam part. Remove old bulb, throw down the street, insert new bulb, all fixed.....

rather then throw down the street, throw itat a wall, you wouldn't want to run it over later, plus they make a cool popping noise

or you could swallow it and listen for an irregular splash in a few days :iceslolan

they go good with salad, and i'm not sure the splash would be the irregular part, hehe
