My Passenger side headlight won't adjust anymore, I'm getting new retrofit headlights soon but I might want to sell these and can't sell them obviously if they're broken. So do I just need a new adjustment piece and replace it? If so where do I find it? I looked on Google but i don't even know what to call it or where to begin looking. I'm not even sure if it's the actual adjustment piece or the headlight itself, any help would be greatly appreciated!
