Abstract
Abstract An aiming post light for artillery and mortar operations at night wherein an ordinary GI flashlight is converted with solid state circuitry to use a blinking light emitting diode (LED) as a light source, enabling ordinary flashlight batteries to last for months of constant use instead of the few hours life in use with previous post lights.
