Not being mean, but 2 days, got to give folks some time to look into it.
What void are you talking about? A sticker? Mine had that, i dont have depos, but halos and it said void all over it, not for hids and such. Did yours come w/ hids or did you put them in? If you put them in, did you have to drill out the hole so that it would fit right? If so, then my assumption is, that its just like mine, and i drilled out incorrectly, meaning not dead straight and i have a hot spot and a U shape on one of my lights. But im not exactly sure why you would have one hot spot though. As far as i know, no you cant put it upside down, at least on mine nope.. and honestly i dont think that would matter on having a hot spot.
Not sure if this helps you at all, but i can try to my best for ya
