I got an HID kit installed in my 2011 Hyundai Elantra and the lights began flickering and going out, so I got the anti flicker/relay kit installed as well. But lately there has been a loud buzzing noise coming from the little box on the relay kit and the passenger headlight shuts off. I was wondering what I should do about this??

I'd say fault relay or fault ballast. Return the HID kit. Get another one.
