Hello, I have a 2018 Nissan Altima S and have a few concerns. I was wondering if the entire headlight assembly is glass or a type of plastic, because of the heat from the HID's. Also wondering how easy it is to put HID's in and ballast placement. Would 55 watts be too much? I just am trying to be careful not to void the warranty because of a electrical fire if it were to happen. I may just be overthinking it but anyone with the same year have any issues installing HID kits for the low beams?
