Model 617GK Tactical Light

Introduction

The Model 617GK Tactical Lights provide 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 two deep
submersion switches built into the H17GK Housing. A two button ON/OFF switch on the left
side, wired in series with the Pressure Switch located on the right side. 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.

Caution

The battery used in the light is very powerful. Be sure that the switch is not touching
anything when the light is stored. If the lamp is turned on while in a case or other container,
the lamp can 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.
If it is necessary to dispose of any batteries, do not do so by fire, mutilation or by
disassembly, as this may cause toxic chemicals to be released.
