You can do 1000>1500>2000 then polish as well. Wetsand until the yellow oxidized water runoff turns to a white,clean color. This means you reached clean, unoxidized plastic. Now finish off with finer sandpaper, and polish the hell out of them. Either work hard by hand or grab a buffer. It'd also be a good idea to wax/seal the headlights like you would your paint.
If all of this sounds too much, 3M makes a headlights restoration kit you can find at your local auto store.
Good luck, and if you need more help feel free to PM me
