I was driving on the interstate the other day and noticed that when I hit a bump, the headlight flickered. Hit another bump and it went out completely. I turned the lights off and back on and it fired up again. Sometimes it fires back up and sometimes it stays off. Is this just a short/loose bulb or would it be the sign of a bulb starting to fail? Would this be a warranty issue?

 

Diiferently bad connection (loose). It would be coverd in a bumper to bumper warranty.
