The lights are on a 04 grand prix and the retrofitted ones were made by someone. I believe they are replacement headlights from ebay but I could be wrong on that. What pictures would you guys need to be able to tell?

The lenses on my OEM lights are discolored so maybe if I bake them I can clean off the inside of the lens and only switch the internals of the headlights? I don't know much about headlights so sorry for the questions
