Headlight out Intermittently - relay? Electical?

[fungo45]

My wife told me that the passenger side headlight on my 2014 was out. I thought she was crazy because a coulple days later, I saw her pull into the garage and it was clearly on. A couple days later, I saw her driving, and it was clearly out. So I bought a new bulb, and it worked fine. For a day.

Now it's mainly out, but every once in a while, it comes back on. Taking the bulb out, it looks fine. I haven't swapped bulbs with the driver side, but the fact that it looks good and that it comes on intermittently, tells me that it's not a simple bulb issue.

Looking at the wires that I can see, everything looks fine. Maybe there is a loose wire somewhere? A short, or a bad relay? I looked in the fuse box and the fuses are fine and I don't see any relays for the headlights. Are they located somewhere else?

Any advice would be great. I don't want to take this in to the dealer if I can avoid it. And of course I'm about 5k miles past the warranty.
