I have an '07 and tonight I noticed my passenger headlight didn't turn on. I turned the lights off and turned them back on and it worked. Has anyone had this happen or know what the problem could be? I hope this isn't some kind of intermittent problem, it would be super annoying.

 

The bulb could have burned out.

 

Burned out and then worked again?

 

I just re-read the orginal post. I originally mis-read it, I've been working way too many hours. If it works intermitantly, I would start by checking all the connections, maybe something is a little loose. Maybe there coulb be a problem with the ballast or ignitor.

 

probably the ballast starting to go bad or the bulb. its not unheard of for the bulb to go out and then come back on (not common, but not unheard of). Most likely the ballast had a short or is failing.

 

It worked again today and stayed on for my hour long commute to work so I hope it was just a bizarre occurrence last night.

Thanks for the info guys.

 

Sounds like the ballast.
