what is the best way to tint your headlights on a 07 subaru impreza?? are there multiple ways? N what are the?

they sell smoked headlight kits for all kinds of cars online. Here is a website you can check out http://headlightfilms.com/osc/index.php

l have a yellow Scion and l tinted it with yellow with the brand 3M film they sell. l did it at car show but can not seem to buy it anymore. It was thick and the colors where clear, charcoal, and yellow. l thinkt hey had red too but l forgot. It looks nice with the charcoal but l can not see well in the dark so l went with yellow cuz it was my fav. color! GL!!!

If you do not drive at night that might look good to you. However it is illegal and since it cuts your light output it is downright dangerous.

you can fit different coloured light bulbs but would'nt recommend it as it dims your light output especially at night

The best way to tint your headlights - NOT AT ALL.
It is unsafe, and also looks pretty lame, like you're trying SO hard to be noticed.
