The highly reflective head of a weapon light is a glaring hole (literally) in the camouflage system of your rifle. The LightCap is a durable, quiet, low profile, and user serviceable cap that eliminates that reflection and fits a majority of weapon lights on the market.

The LightCap is designed with an integral lever that allows the shooter to flip the LightCap off the bezel of the light for rapid deployment of the white light. The included ranger band allows the LightCap to be retained near the bezel when removed so that it can be quickly placed back over the bezel.

The LightCap also acts as a safety against negligent light discharges that would reveal the user’s position. This is especially important if running night vision and IR laser/illuminators where an unplanned white light discharge could be catastrophic.

Weapon lights are not the only application for LightCap. They can be attached to helmet flashlights or any other rail mounted lighting solution you might need.


INCLUDES: 1x LightCap, 1x Ranger Band, 2x 12” sections of shock cord


The LightCap is made in the USA from an incredibly durable, UV-resistant thermoplastic. The LightCap is affixed with American made, rubber core shock cord and the included ranger band is made from EPDM Rubber with outstanding heat, UV, and saltwater resistance.

When properly tensioned, LightCap should not “rattle” during movement. To properly tention, first ensure that the ranger band is installed far back enough so that the LightCap can completely clear the bezel when flipped to the side. In this position, remove slack by pulling on the shock cord behind the ranger band.

    Simple, easy to use, field repairable. Great for reducing frontside signature while not adding much weight or many more failure points.

    Got one for all my modlites. Install video on YT helped tremendously, fitment of ranger band is tight and secure. Cap functions as advertised. Helps with light discipline and prevention of AD

  3. Zach Luna (verified owner)

    Great cover with easy install it’s definitely a must have for all lights!

    Got one for every light I own – absolutely love this product… firstly, it protects your light head, secondly, useful as an “anti-reflection device” and perfect for avoiding negligent light discharge under NV.
