Oxidized headlights?

Asked by Aug 14, 2016 at 10:21 AM about the 2006 Mazda MAZDA3 Touring

Question type: Maintenance & Repair

Hi so i dont know much about cars, i just want to
throw that out there because im new to this. My
headlights have a very dark oxidized look towards
the bottom to where its keeping all the light from
exiting using my low beams. I tried toothpaste and
that didnt work. Ive looked online for other things
to try. It almost looks like water sitting inside but i
do know for a fact its on the outside. Any
suggestions on how i can get this off? Please help!
I would attach a picture if i knew how lol

If you have water sitting inside the headlamps, it's time to replace them. The seal is compromised. Some will say to drill a small hole to drain or remove and dry out, but temporary. Toothpaste and rubbing compound will help with oxidation on the outside only and is temporary as you always have to buff them. UV is killer on plastics. If you like the car and want to keep it, buy new ones. rockauto.com has them for $100 a piece. It will make your car look like new again.

Yeah it is on the outside it just looks nasty. New headlight covers right? Thank you so much for responding so quickly. I appreciate it! I even tried sugar mix and a scrubber but that didnt work hahah

I just got this car two days ago so i def want to keep it looking nice. The only cosmetic problem is how the headlights look. But also driving at night on two lane roads i need to be able to see

On your car, you can't just replace the covers, a whole new headlight assembly. I suggest you get the TYC ones.

I realized that when i looked it up on rockauto. That sucks. Ill look into tyc! Thank you Tom for your help :)

You -- or a friend? -- can do this pretty cheaply. ChrisFix YouTube'r is the best I've found: https://www.youtube.com/watch?v=UEJbKLZ7RmM&t=0s Good luck.
