I hope it is, there's even a possibility that you just have a loose wire or a blown fuse somewhere in the hood.
When my starter wasn't working, the ends of the bulb were lighting, but not the center. Since yours has no lighting at all, I'd open it up and make sure there are no loose connections before completely replacing anything.
I tried tweaking everything to make sure it was all in there soundly, but it seemed to be to no avail. The starter seems a good culprit, though, as for a long time I had trouble with it not lighting up. I assumed it was the switch, which was (one of) the reasons I got a timer-- that way I could leave it on and not have to worry about the switch. It's hard to say, but at least the starter is a cheap thing to try.
