By haze, do you mean foggy lenses? The covers on my headlights were hazing, like covered in a fine film of dirt on the outside, I just used some of the polish I use on my paint and it buffed right out, then I covered the lenses with a coat of wax and buffed out......they look brand new! I never had foggy lenses from the inside, but by reading many posts here have found that many have had this issue and there was a TSB issued on this. Good luck!!
