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

I like this product mainly because I can use it at night and if I go from red light to no light, my night vision is not effected. Also, if I need to temporaly blind someone, with the flip of the cap, I can go to a blinding white light. This is a very nice product but I think it is a bit expensive. So, while I own several lights that I could use this device on. However, due to the price, I am forced to be very seclective on how many I purchase and on which lights I outfit with this device. Hopefully the price will come down soon.
Pros: Secure fit, red light does not impair night visition, allows quick conversion to normal light
Cons: Price
