Go to Ebay and do a search for Janvil. It's a plastic polish that I've used
and it works really well just by hand. Add a small polisher like you can buy
at wal-mart for about $10 and you can make them look almost like new.
I'm a big believer in using toothpaste as a very mild plastic abrasive. I've
used it for years with good results on a number of projects. Pencil erasers
also work for smaller areas like scratches.
If you use the toothpaste, be cheap with it. The more you put on there, the
less friction you'll have with which to polish. Then flood it with water to get
rid of it.
Assuming the discoloration is on the outside, try this. If you have an orbital
polisher, try it on the lenses with come "coarse" compound. Follow with "fine"
compound then clean and spray them with clear epoxy finish. After polishing,

I used Meguiars PlastX on a 98 Chevy Metro with headlight lenses so cloudy
that high beam was useless. Just one easy application and it was amazingly
clear. I tried the same stuff on a Dodge D50 pickup with almost no effect.
The Dodge almost looks like the problem is on the inside of the lens.
Meguiars was on the shelf with the rest of the auto polish at Kragen's.

It is a result of improper maintenance of the lenses. Get yourself some of
the stuff that is used to clean motorcycle windshields, WBMA. After you
have them cleared up use a polymer polish, like NuFinish, a few times a year
to keep them clear.
