Model 318FH & 618FH Waterproof Tactical Light
Introduction
The Model 318FH & 618FH Waterproof 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. A two button ON/OFF switch is on the left side of the H18FH Housing and a
Pressure Switch is on the right side. The switches are wired in parallel. The ON/OFF
switch will turn the light ON or OFF. Press on the Pressure Switch and the light will come
ON, release pressure and the light will go OFF. The Pressure Switch is stiffened to prevent
turn on during deep submersion. A Switch Blocker is provided for users that want to reduce
the functional size of the pressure switch.

overheat and damage the light or surrounding materials. Remove the battery or unscrew the bezel
far enough to prevent the lamp from turning on when stored.
Do not use a 3 Volt Lamp in a 6 Volt system. The lamp will BURN OUT immediately!!! To
identify a lamp assembly: the 3 volt lamp has a Red label and is marked R30, the 6 volt has a Blue
