Introduction
The Model 318FG & 618FG Tactical light provides a rugged and reliable source of high
intensity light that is integrated into the fore-arm of the shotgun. The lamp is shock isolated.
There are three switches built into the H18FG Housing. A two button ON/OFF switch on the
left side, wired in parallel, provides the means to turn the light ON and have it stay ON until it
is turned OFF. A two button ON/OFF switch and a Pressure Switch are located on the right
side and wired in series. When the ON/OFF switch is ON the Pressure Switch will turn the
light ON when pressure is applied to the switch and OFF when pressure is released. When
the ON/OFF switch is OFF, the Pressure Switch is deactivated. A Switch Blocker is provided
for users that want to reduce the functional size of the Pressure Switch.
