What's the cheapest way to blackout (smoke) 09 Mustang taillights?

Cheapest way to blackout (smoke) the taillights is to purchase a roll of window tint (you can buy it at any auto parts store or even wal-mart)... Just follow the instructions, or look up the instructions for installing window tint online. It is simple as long as you cut the film correctly. When you buy blackout film from the internet, it is only window tint cut to the size of the tail light.
