This is an adjustable brightness pressure pad that is compatible with our KZ500 flashlights. This pressure pad will allow you to turn on the light from the pressure pad and then adjust the brightness up or down to 1 of 20 different brightness levels. The light will remain on until you turn it off or dim the light all of the way down. When you turn the light off/on it will come back on to the brightness level you last used.
Please note the tail cap will look slightly different. Operation and pressure pad are the same.
