If your plastic headlight lenses on your car turn
yellow start sanding them
with 600 grit wet and progress to 2000 grit wet.
They will come clear
and like new. This will work for  scratches in your
aircraft plexi windshield
as well.

When I visited a headlight manufacturing plant they
said they clearcoat the lenses with UV blocker to
prevent yellowing. Maybe they will turn yellow again
after sanding.

Only takes a few minutes. I am sure the headlight manufacturer
does not want you to know this. God knows how much money they
make selling replacement lenses :)
