restore rear lights

I would appreciate any help you guys could offer. I just picked up my rear lights from the body shop. they are dull and I would like to polish them. is there any product out there that will restore them to a clear, shiney finish? thanks

Try Mothers mag wheel and aluminum polish. Works great on plastic. I have used it on my gauge lenses and it worked great.

Thanks, I have some. I'll try it this week.

Tooth paste works wonders polishing plastic lenses. Rub it in with a clean, soft cloth then buff. You will wonder why you haven't been using it all along.

polished them last night. came out great. started with Mother's, then Scratch Out by Kit (don't know where or when I got it. seemed to be a finer grit than Mothers), finished up with Crest tooth paste. thanks all for your input.
