Surefire fm35 red filter - SureFire FM35 Red Filter for flashlights with 1.25" diameter bezel (Z2, C2, C3, G2Z, G2, 6P, 9P )

The red filter is an exceptional light source in low light conditions to maintain your night vision. But it is easy to switch between the filtered and unfiltered mode as your lighting needs changes.
Pros: Well build and solid product.
