Is it possible to break a headlight by shorting wires in window switch?

Hi all. I have a friends car who's passenger side window was stuck down, and the switch was broken. In an effort to help, I got out my voltmeter and identified the ground and 12V wires. There were five wires, including ground and +12V, and two other wires went to the window motor. I accidentally shorted the 12V wire to the 5th 'mystery wire' and it sparked a little. I eventually figured out which wires to connect to make the window go up.

I read later online that this is for an LED in the switch that is on at night (when the headlights are on). I mentioned this to my friend, and it turns out, that his passenger side headlight doesn't work anymore! But it worked before. The brights work, but the normal light on that side of the car doesn't work. Is it possible that I broke some electronics that drive the headlight? What is the best way to fix this? Is there some fuse to replace? Some control board I can order and plug in somewhere? What sort of cost might I be looking at? Or is it just a coincidence?

This is a 4 door, ford sedan, maybe 10 years old. I wish I could be more specific. Thanks so much for any insight!
