Keep your HellFighter shinning bright indefinitely without needing batteries with the SureFire HellFighter Power Cable Adapter for 12 Volt Accessory Socket. This cable is for the original HellFighter light and enables you to use a vehicles accessory socket or cigarette lighter to be used as an optional power source for the WeaponLight. It includes a screw-on cap to help protect the lug end when it is not in use and to prevent short circuiting.
