I like the yellow headlight for visibility (daytime), won't blind/upset cagers and has kind of an Euro look.
The film also protects the headlight from rocks/pits.
I already lost one due to a huge meteor, that smashed the headlight.
It was easy to apply on the flat face, but hard around the corners even with a hot air gun, due to thickness of the material.

Forgot to say, I have had a Kisan Path Blazer for years and it has been flawless.
Paid a lot less than what is advertised here.
