This Flip Cap Lens from Insight Technology is compatible with Insight's HC-120 and HC-150 Flashlights. The Flip Cap Lens attaches to the head of the flashlight, and it can be flipped down to change the color of the light beam. Its anti-roll hex shape stabilizes the light when placed on an incline.

This green Flip Cap Lens can be used when hunting at night - the eyesight of most wild animals is least sensitive to green illumination. Because it reduces the flashlight's intensity, it's also useful for close-range non-tactical tasks such as map reading.
