Your purchase of a Wolo warning light bar is the perfect choice to compliment your vehicle. Wolo’s warning

lights are manufactured with the ﬁnest materials. Before being packaged, each light is tested to meet our high

standards and ensure a perfect working light. Our quality workmanship and components are Wolo’s assurance

Before installation of the light bar is attempted, it is important to read these instructions completely. The lives of

people are dependent on a proper installation of the light bar to the vehicle. The person installing this light bar

must have advanced knowledge of the proper method for mounting and securing the light bar to a vehicle’s roof

or exterior, as well as knowledge of the vehicle’s electrical system. Again, read this manual completely and note

any messages marked “IMPORTANT” or “WARNING’’. A safe installation will prevent serious injury or damage

to the vehicle.

ON PATROL comes completely wired and does not require any internal wiring by the installer. The power cable

has all the required wires with factory installed terminals and connectors for a successful installation.

Installation of the ON PATROL Light Bar requires drilling into the vehicle. The installer must carefully inspect both

sides of the selected locations to ensure that there are no components, wires and/or any other vehicle parts that

could be damaged by drilling. IMPORTANT: Always de-burr any drilled holes, ensuring that there are no sharp

edges. Install a rubber grommet into all metal holes that the wires are being routed through.

Always refer to the vehicle’s shop manual for the deployment location of air bags. Never install the light bar’s

switch control panel, wires and or components in the deployment area of any air bag. Improper installation

could reduce the effectiveness of the vehicle’s air bag system and/or project an object that could cause serious

personal injury or death to the driver and passengers. The user/installer assumes all responsibility to properly

access a safe mounting location of the light bar’s control panel, which will provide ultimate safety to the driver

and passengers inside the vehicle.

The vehicle operator and or maintenance department should inspect the light bar frequently to ensure all brackets

are securely attached to the vehicle and that all mounting hardware is free of corrosion.

The light bar’s control panel should be mounted in a location where the switches can be easily reached. Never

attempt to turn this light bar on/off when driving under hazardous conditions.

These installation instructions should always be kept and stored in a safe location, so that they can be referred

to when information, maintenance or reinstallation is required.

Failure to follow all safety precautions and installation procedures outlined in these instructions could result in

property damage to the vehicle, serious injury or death to you or others.

MOUNTING LIGHT BAR

1. Place the light bar on the selected location of the vehicle’s roof. A preferred mounting position on the roof

is close to the B-pillar, which is the strongest part of the roof. IMPORTANT: Make sure the light bar is

facing the correct direction. NOTE: There is a label on the light’s front lens indicating the correct direction

to mount the light bar.

2. Make sure the selected location of the

light bar will allow the stainless steel

straps to attach to the vehicle window

ledge on both the driver’s and passenger

sides. See ﬁg 1.
