Now your Surefire and many other tactical lights can have a feature found on lights costing over $200. This replacement tailcap offers a strobe function. Called the Lightsaver Blitzer tailcap, it's a direct replacement for the standard tailcap on a number of SureFire systems. It's available to retrofit SureFire incandescent lights like the G2, Z2, G2Z, G3, 6P, 9P, C2, C3, M2, M3, M3T, M4, L5, L6, M951, M961, M971, M981 and most SureFire Classic Universal Weapon light systems and other brands with similar dimensions.
Please note that this tailcap is not compatible with LED bulbs and LED bulb conversions. Attempting to use this tailcap with an LED bulb will burn out the electronics, rendering the tailcap useless.
