WIRELESS MAGNETIC TOW LIGHT
Model: PY-937
This product is intended for temporary use to provide tail light function as well as stop and turn light when
towing a vehicle narrower than 80 inches wide. Only use with standard 12 Volt vehicle systems.
Limitation:
Do not operate towing lights farther than 19.8 meters (65 feet) from the transmitter.
Transmitter and Vehicle Plug Wiring Scheme:
White –Ground
Brown –Tail / Running Lights
Yellow –Left Brake / Left Turn Signal
Green –Right Brake / Right Turn Signal
Operating:
1) Install AA size batteries into both “LH”and “RH”light base per indicated polarity.
2) Connect the transmitter to your “four-flat”trailer plug on the vehicle.
3) Clean the mounting surface and transmitter’s magnetic base. Then attach the transmitter to a steel surface
in the rear of towing vehicle.
4) Lights should be placed at the same height. Don’t mount both lights lower than 38.1cm (1.25 feet) or
higher than 1.8M (6 feet) from the ground. Attach the “LH”and “RH”lights on a flat surface as practical
and at an equal distance from the sides of the vehicle being towed. The entire magnet must touch the steel
surface for optimal holding performance. Place lights to allow following vehicles optimal visibility at all
times. If the lights aren’t aligned properly, detaching them by tipping the light to disengage the magnetic
base before placing them again.
5) Don’t cover or obstruct the lights during operation. Use a tie wrap to collect any loose cable between the
lights.
6) Turn “ON”the switch located on the bottom of the “LH”base.
7) Verify the function of left/right turn, tail lights and stop lights. Do not drive your vehicle unless all lights
function!
8) Switch off the lights after each use. If the lights are stored for longer than one month, please remove the
batteries and store batteries at room temperature to avoid battery leakage. Do not allow the magnetic
bases to come in contact with each other.

Important:
1. Every 2 hours confirm that your brake, turn signal and running lights are operating correctly. Do not
operate your tow lights if the vehicle has faulty wiring or if some or all of the lights do not light.
2. For temperature below 20℉batteries may need to be changed more often. The LED near the top center of
the “LH” light will blink amber if battery power is low. Immediate install all new batteries in both tow lights
to ensure safe operation and to meet SAE/FMVSS 108 safety standards.
3. Do not submerge the lights or transmitter in water. Damage may occur.
4. Always have a spare set of eight AA batteries on hand, especially if travelling for an extended period of
time.
Troubleshooting:
1. If your towing vehicle has rear turn signals separate from the stop light, a LED light Bulb load-Resistor Kit
available from an automotive accessory supplier may be necessary for turn signals to flash properly.
2. If one or both tow lights do not function, check and/or replace all batteries. Placing four batteries into each
base with polarity as indicated.
3. If left / right turn functions are reversed, then reverse the yellow and green wires to the transmitter.
4. If only some lamp functions work while others do not, look over the wiring diagram and check that the
four-flat trailer connector is wired correctly.
5. Check the connection between the “four-flat”plugs for corrosion. Remove corrosion with baking soda and
a small disposable brush while wearing gloves.
