I bought some plastic polish from Autozone for like $4 and after 3 applications it has really improved the appearance of my headlights! The yellow discoloration is almost gone, and the clarity of the plastic looks waaay better!

You can polish the headlights with a small scratch remover. Eagle has one, and other companies do too. If you do a search for cleaning of headlights, you will find many products that work. I have seen some go from a yellowish color to a clear lense in about 5 minutes. It is worth a try first, then if you need to, shake and bake!
