Protecting plastic headlights

[marblegary]

My last headlights went yellow/cloudy, i was too lazy to restore them so just bought new ones, now how do i keep them looking sparkly/crystal clear, is there something i can put on them at all? (dont want them plastic headlight protectors on it, although its sunlight that damages them i think, so may not work anyway?!)

In case they get scratched or "corroded" or can polish them and they will be almost as new,

If they are really scratched try using moisted 2000 sandpaper on them before polishing them with a yellow pad.

I dont think there is any specific product to protect them... you could try grojet2000 or any other type of sealant but I have no idea of what would be the results
