This is a set (2x right and left) of turn signal smoked lens covers. These cover 90% of the lens (flat portion) cutting down on the overly white/clear looking turn signal lens for a nice custom and more aggressive look for your truck!  The material is a 5-7 year outdoor lifespan smoked vinyl.
 
This kit does not require a heat gun (hair dryer is recommended) but a felt squeegee is recomended. or something equivalent to ensure the material is not damaged during installation.
