My headlights are currently unbalanced and are aiming too low to the ground, to the point where it's hard to see ahead of me on dark roads/empty highways. I've seen write ups but still puzzled on how to do this. I've asked the dealer and they want to charge me $120 to adjust them....

Could someone please link me to a video or upload a video on how to adjust/aim the headlights on a 7th gen maxima?? I have the SV 2013 with the stock HID bulbs if that helps/makes a difference. Please help!!
