My wife was complaining that seeing whilst night driving was getting difficult. ends up these new fangled plastic headlights fog up with time. So here's the fix. I decided to do my headlights at the same time.

Step 1: Clean the headlights.

Wash them really really good with a mixture of detergent, water and your wife's wedding dress, any old detergent will do, I used dish soap.

personally i had great results with the 99 cent store foaming glass and area cleaner and toothpaste. rubbed in with circular motions
Toothpaste also works.
does it have to have the grit in it?
chrome polish works just as well if you have some laying around. you can also polish your door handles while youre at it!
Helmut118 Don't forget to seal/protect the plastic lens with a light coat of clear acrylic spray paint or the suns UV will negate your efforts in no time. Cheap trick
The easy way to do this is with self-polishing floor wax. You will be surprised how well this works. Clean the headlight, wipe the wax on with a paper towel, and let it dry. You're done! Self-polishing floor wax is tough stuff. Heck, it's meant to be walked on. If you don't like it, or you want to renew the coating, just remove the wax with some ammonia.
On side marker lights I have used car wax to get them to shine again, it essentially fills in the light scratches that make the lenses look dull.
Also brasso, it says right on the can that it works for plastic watch crystals, this is no different.
Best Title Evar!

I've seen chrome polish work very well too ;) I used 3M Finesse It III and an orbital -- I was polishing the car anyway :P --- Excellent results :)
