Do you have yellowing headlight lenses?
The headlight lenses on our campervan were yellowing with age and most of the lacquer film has come off; they may have been an MoT failure due to the colour. I rubbed some toothpaste on them this afternoon, rinsed them off and applied car polish. They look almost as good as new now. Whitening toothpaste is reported to be better than normal toothpaste but I just added a bit of baking soda paste for a bit more abrasion.
