Metallic rattling noise

[B16B]

i actually found out what is it. There is a circular part/sensor i think not sure what is actually or what it’s for. It sits between the bumper and the frame of the car next to the intercooler on the passenger side. It vibrates when you close the door.
I was able to slide my phone down in the engine bay to take a quick clip of it.

Good find. That appears to be the horn bracket.

Interesting lol. Out of all things! i never thought it would related to the horn. I thought it couldn’t be some kind of temp sensor to the intercooler or something related to the AC!
