So these two fixes I've come across over the past year and I thought I would share them. My wife told me that she read you can use toothpaste to get the oxidation off of headlights. I used a tube of crest that had baking soda and peroxide in it and with a little bit of buffing the stuff came off almost instantly!

Another fix, my friend gave me this HID kit he bought that he couldn't get working, as I examined the ballasts, the input and output sockets were covered in rust. So I used a bottle of coke and soaked them overnight. The next day one of them was working, the other ballast still has a lot of rust so I'm going to let it soak a little more. So if you look on craigslist and find a broken set you might be able to fix them. Also might be something worth inspecting if your HID kits ever fail. Especially if you live in a place that has rather salty air.

Anyways, just wanted to share.
