Abstract
A laser aiming light for firearms includes interchangeable switches for selectively limiting the laser output to an eye safe level for training purposes and for providing full power for operational use in a combat zone. A capability for using a remote switch is provided. As the output of the laser diode and associated components are temperature sensitive, temperature compensating circuitry ensures adequate power at high, as well as at low, ambient temperatures. Power is provided by enclosed conventional batteries retained by a sealed cap maintained in place by a pivotally mounted retainer and locking mechanism.
