One of my headlights isn't working

Hi, a few weeks ago I had a low speed crash into a small tree, nothing major just wheel alignment and put a rectangle shaped hole in the front bumper near the bottom.
Since then I have noticed that the right headlight isn't working, full beam works fine and the park lights work but just low beam isn't. I have tried replacing the globe, checked the fuse and relay in the engine compartment.

I was thinking that maybe I damaged the earth wire or something when I hit the tree or possibly damaged something else. But the engine compartment is so small in this car that I can't get my hands in there to have a look. Do you have any ideas as to where I should look first?

Thank you, Any help appreciated.
