YES. One of the coolest things about these tactical lights is the ability to add a colored lens to the end of it, or rather to swap out the existing lens with one. You have to purchase the colored lens separately, but often times they are available as part of a set including red, green, and blue among others. However these colored lenses are not interchangeable between brands, so it is important to make sure you are getting one that fits your flashlight of choice.
