GETTING TO KNOW YOUR SNOWPLOW

SNOWPLOW COMPONENTS

A snowplow consists of all the components that are 
readily removable from the vehicle as a unit. This 
includes the blade, A-frame, lift frame, hydraulic unit, 
and snowplow headlamps. The snowplow is ready and 
easy to mount when you need to plow snow. When 
plowing is completed, remove the snowplow.

NIGHTHAWK™ SNOWPLOW HEADLAMPS

The NIGHTHAWK snowplow headlamps include a 
set of rectangular, dual-beam, halogen headlamps 
plus combination park and turn signals. A pre-wired 
harness with a plug-in module requires no headlamp 
wire splicing. The headlamps conform to Federal 
Motor Vehicle Safety Standards (FMVSS).

When the electrical plugs are connected, the vehicle 
headlamps will automatically switch to the snowplow 
headlamps when they are turned ON. When the 
electrical plugs are disconnected, the headlamps will 
automatically switch to vehicle headlamps when they 
are turned ON.

Replacement parts are available through your local 
WESTERN

®

 outlet.

VEHICLE MOUNT KIT

Mount kits have been designed for most vehicles. Due 
to the differences among vehicle models, the kits are 
not interchangeable.

The vehicle mount assembly is bolted to the underside 
of the vehicle frame, and the receiver assembly is 
attached to the vehicle mount. It is engineered to 
provide the primary connecting points between the 
snowplow assembly and the vehicle. The weight of the 
snowplow system is distributed to the frame of your 
vehicle by the mount assembly.
