Surefire FM16 Filter for 1.62" bezels. Has a tint black scratch on the front you can see in the picture, doesn't affect function. Very big, but easy to shim it on smaller flashlights. Surefire's FM filters are made of dichroic glass and are discontinued, so they tend to be expensive with on/off availability. $25 shipped. Paypal, Venmo, Zelle
