I want to make my head lights abit darker to blend in with my black car as I really like the look of this.

Ive looked at fly eyes, & when ive seen far away pictures it looks amazing, but up close I really dont like the look of it.

Ive been told about a film you can put on your lights, ive also looked at this already but as know it has to let a certain amount of light through, I need to find one that I know is legal.

Can anybody shed any light on this?

Thanks :)
