Folks how do you clean them mine always look dull and slightly yellow thanks
 
You can either buy a headlight restoration kit from Meguiars or 3M for example and use the contents to refurb the lens or get some wet and dry paper starting with 1200grit going up to a fine 3000grit with soapy water and rub them down. Finish with a polish on a rotary drill and a sealant.
 
I bought the turtlewax restoration kit which I'd heard good things about but it wasn't quite strong enough. Mine were quite bad so I started at 600 grit, then 800, 1500 and finally 2500 before using t-cut on a drill rotary polishing wheel and finished with the turtlewax headlight polish from the kit. You probably don't need to start at 600 if they're not too bad. I don't think there's a hard-and-fast sanding sequence, as long as you get the yellow plastic off and go up high enough, the polish is what makes it clear at the end. Also, I'd recommend the spray headlight clearcoat by 'e-tech'.

P.s. It's a lot easier if you can take the headlight off the car!
