Probably better off just buying new ones. I bought both sides for my 2010 Impala for around $75.00 a piece from Amazon. Usually cheaper if you buy them in a set
Meguiar's PlastX (rubbing compound) and Meguiar's headlight coating (spray can)My headlights have always been cloudy, after all my car is like 23 yrs old. Last year, to pass inspection, my mechanic says he cleaned it, unfortunately whatever he did made them worse, so much worse. I have tried toothpaste in the past, smh, doesn't work, but I need to do something now. The thing is, when I look at the headlight, it looks like the issue is inside, not on the outside, like everything I can find on the subject. I also can't find anyone local to do this, but do they also do the inside? Here are some pics, which actually look slightly better than IRL. If I remember I'll try to take some at night. First two are before I cleaned then. The second two was after cleaning them with baking soda, they were still wet. The fourth pic was after it dried. The I made the mistake of using tooth paste to see if it would help more, it made it worse, then I used baking soda again and the result is the last pic. I should have left well enough alone. The lights are still really dim, wonder if I need new bulbs. View attachment 56555 View attachment 56556

As having this happen on many vehicles. All of the Gimmick cleaners only do the outside. You are correct in your assumtion of inside fog. Once the plastic gets that oxydation on the inside, youy MUST replace the entire "Bucket" assembly. BTW, what is your car info> wear, make. etc?
As other person said, Get Both Heasdlight assemblies through Amazon, $120 - $180 per set, There are several makers of these, so take your time, check out the seller, read reviews, then if needed, the folks here on the Forum can give you any install tips
if the plastic coating looks hazy or off colored and not clear replacing the bulbs will not help. Better off just replacing the entire headlight bucket
