Remove amber film on headlights

[cubbyno9]

Hi all, I know I might be repeating previous questions.
I have a pair of headlights with the orange tint on the outside and I am trying to find a way to remove the orange.
I have found on the forum a way to remove the orange tint from inside the headlights but surely there must be a way remove the orange tint that is on the outside.
When running hand over headlight you can feel an edge/lip from the orange color, so does anyone have any advice.

Thanks in advance.
