Warnings and Notices for Users and Installers

This document must be delivered to and read by the end user and installer as it serves to provide you with the required information for proper and

safe use of your STL product. Before operating this or any STL products the user and installer must read this manual all the way through. You will nd

important information in this manual that could prevent property damage and/or serious injury to the user and installer.

STL products are intended to alert pedestrians and other operators of the presence of personnel, the operation of emergency vehicles, an emergency

site, and any warning needs. This does not ensure that pedestrians or drivers will react, heed, or observe emergency warning signals. Nor does the use

of emergency signals grant or ensure you the right of way. It is your responsibility to make sure you can proceed safely before driving against tra󰀩c,

entering an intersection, responding at a high rate of speed, or walking on or around tra󰀩c lanes.

Your STL emergency vehicle devices should be tested daily to ensure the device and all its functions are operating correctly. If you experience a

malfunction contact STL’s Customer Service immediately for troubleshooting options, or a warranty or service claim. You must ensure that the projection

of the visual and audible signal is not blocked by vehicle components (i.e.: open trunks, visors, compartment doors), vehicles, other obstructions, or

people.

This is professional grade equipment and is intended for strict use by authorized personnel only. It is the user’s responsibility to understand and obey all

laws regarding emergency warning devices. You must know and be familiar with all applicable city, state, and federal laws and regulations prior to the

use of emergency vehicle warning devices.

SpeedTech Lights, Inc assumes no liability for any loss resulting from the use of this warning device. Proper installation is vital to the performance of the

warning devices and safe operation of the emergency vehicle. Since the operator is under stressful environments the equipment must be properly wired

and mounted to ensure e󰀨ectiveness and safety. Therefore controllers must be properly installed and placed within convenient reach of the operator so

eye contact with the roadway is never lost.

The e󰀨ectiveness of your STL equipment is highly dependent upon correct mounting and wiring. Improper wiring and mounting of the warning device will

reduce the output and performance of the equipment. Emergency warning devices frequently require high electrical voltages and/or currents. Properly

protect and use caution around live electrical connections. Grounding or shorting of electrical connections can cause high current arcing, which can

cause severe personal injury and/or serious vehicle damage, including re.

Electromagnetic interference can be caused by many electronic devices used in emergency vehicles. To ensure that this doesn’t happen to you, Light

Bars should be mounted a minimum of 12” - 34” from the radio antenna and do not power your equipment from the same circuit or share the same

grounding circuit with radio communication equipment. After installation, test all the vehicle’s equipment together to ensure everything operates free of

interference.

Driver and/or passenger airbags (SRS) will impact the way you mount your equipment. Any equipment installed in the deployment area of the airbags

will damage or dislodge the airbags and sensors. This will also reduce the e󰀨ectiveness of the airbags to protect the passengers and therefore these

areas must be avoided. Installers must make sure that this equipment along with any parts, hardware, wiring, power supplies, and switch boxes do not

interfere with the airbags, SRS wiring, or sensors.

All STL equipment needs to be mounted and installed according to the vehicle manufacturer’s instructions and securely attached to a part of the vehicle

of su󰀩cient strength to withstand the forces applied by the equipment. This device should be permanently mounted within the zones specied by the

vehicle manufacturer. This especially applies to equipment mounted on the exterior of the vehicle to avoid dislodging. Mounting units on the interior of

the vehicle by a method other than permanent mount is discouraged as it may become detached under aggressive driving conditions such as sudden

braking, collision, or swerving.

PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL

TO ENSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.

Unpacking Your STL Product

• Unpack your unit to identify all parts including but not limited to: Light Bar, switch box, brackets, screws, bolts, wiring harness, fuses, etc.

• Some parts may be in small bags.

• Some products may be packaged inside boxes of other products.

• Some parts such as Gutter Brackets, may be in the foam protection. Double check that no parts are left within the foam protection or left in the box.

Important Points for Your Safety and Longevity of Your Light Bar

• Installers are required to have a good understanding of automotive electronic systems and procedures for proper installation.

• Never stare directly into the LEDs as momentary blindness and/or eye damage may occur.

• Never take any lights through a car wash. Use only water to clean the outer body/lens of your equipment.

• Never use a pressure washer to clean any STL products. Inspect and test your product daily to ensure it operates properly and is mounted

correctly.

• Never cut wires or work on a unit while the unit is still connected to a power source.

• Never install this product or route any wires through or in the deployment area of the airbag. Doing so may cause serious personal injury as it will

damage or reduce the e󰀨ectiveness of the airbag by causing the unit to become a projectile. Reference the owner’s manual for your vehicle to nd

the airbag deployment area. The User/Installer assumes all responsibility to determine proper mounting location, based on providing ultimate safety

to all passengers in the vehicle.

• If the product requires you to drill holes, the installer must ensure that the drilling process does not damage any vehicle components or other vital

parts. Check all sides of the mounting surface before beginning to drill. Make sure to deburr all drilled holes and remove any metal remnants or

shards to avoid injury and wires from becoming spliced. Grommets are to be installed in all wire passage holes.

• Grommets, cable ties, looms, and other installation hardware should be used to anchor and protect all wiring. Fuses should be properly sized and

located as close to the power take o󰀨 points as possible to protect the wiring and device. To protect against short circuits, a fuse is included by STL

for all products. DO NOT use a fuse with a higher amp rating than the initial fuse included by STL for all products.

• Insulation displacement connectors are not to be used.

• In order for STL products to operate at optimum e󰀩ciency, a secure and good electrical connection to the battery’s Ground Post must be made. The

recommended procedure requires the unit’s ground wire be connected directly to the NEGATIVE (-) battery post. DO NOT use Circuit Breaks.

• Instruction manuals should be stored in a safe place for reference if you need to reinstall the unit or perform maintenance. They can also be

found at the main site under the product listing at www.SpeedTechLights.com. If your product is no longer available on the website contact STL’s

Customer Service at 800-757-2581 for assistance.

• If your product requires the use of a control box or remote device to turn on and control your equipment, make sure it is installed in a location that

allows both the user and the vehicle to operate safely in any driving condition.

• Never activate or control your equipment in hazardous driving conditions.

• Use SXL type wire in the engine compartment where higher heat resistance is required according to SAE J-1128. All wires should be in accordance

with the minimum wire size and other recommendations made by the manufacturer and be protected from hot surfaces and moving parts.

• FAILURE TO FOLLOW THESE SAFETY PRECAUTIONS, WARNINGS, NOTICES, AND INSTRUCTIONS COULD RESULT IN DAMAGE TO THE

PRODUCT OR VEHICLE THAT WILL VOID YOUR WARRANTY AND/OR CAUSE SERIOUS INJURY TO YOU AND YOUR PASSENGER.
