Lamp ot warning light

This morning when I left to go to work and turned my headlights on, the lamp out warning light came on. I had my high beams on and check my lights. The driver's side headlight was out. I switched back to the low beams and rechecked. The headlight was now on, but the lamp out light was still on in the dash. I then switched back again to the high beams, but this time the high beam came on. When I switched back to low beams, the lamp out light went out. The lights have worked since then and no problems. Has any one else had this problem or could this just be a fluke?? We have had our first cold spell here and it was 39 degrees this morning. Maybe the cold had something to do with it..... :(

I haven't had a problem with the warning light. I have bumped the front of mine and every now and then the lights will be off until I hit the high beam. They'll come on and then be fine, sometimes when I dim them they go off so I guess I've jarred something up front. Air bag light comes on too now.
