1. Plug the transmitter into your vehicle’s 7-pin socket.
2. Turn on the power switch located beneath the handle. The 3/4″left side marker light will illuminate indicating the power is on.
3. Within seconds when you turn on the power, the outer lights on the bar (turn signals) will illuminate quickly and stay on for 2 seconds. This shows you that your battery is fully charged. If ONLY the left hand turn stays on for 2 seconds, then your battery is at least ½ charge capacity. If no lights stay on after you turn on the light bar, then you need to charge the batteries as soon as possible.
4. The tail lights will not turn on when you power up the bar, only when the tail lights or headlights in the towing vehicle are turned on. The same for stop and turn signals. This will dramatically increase the battery life between charges.
5. Test the markers, left and right turn signals, and brake lights.
6. In the event that you should discharge the batteries to the point that they will not operate the wireless light bar, you can plug a cable into the charging socket on the left side of the bar and operate it just like one of our wired light bars. This will not charge the bar, just gives you operation until you can charge it normally. 

Keep the bar on the charger when not in use. The batteries will resist developing a memory so you do not have to discharge them all the way. However, they must be charged on a regular basis to prevent them discharging to a very low voltage level.

Wire the included plug to an available 12V power source for charging as follows:

Power to red wire(this wire has a fuse in it) – Ground to black wire

Then plug it into the charging socket on the left side of the bar. A 5 amp fuse is already installed.

When the bar is charging, the GREEN LED near the socket will light. If the LED is not lit, check your connections to make sure that you are connected to full time power. 

If you have further questions, please call 800-490-3158.

1. Plug the transmitter into your vehicle’s socket.
2. Turn on the power switch located beneath the handle. The ¾” LED left side marker light will illuminate, indicating the power is on.

1. Plug the transmitter into your vehicle’s socket.
2. Place the units so the amber strobes are toward the outside of the vehicle and the rocker switches are on the inside.
3. Turn on both units using the top rocker. It will illuminate with a small LED.
4. To operate the 2.5” amber strobes, turn on the main rocker switch with the small LED light and the second rocker switch located below it and the strobes will flash. You can operate the lights with or without the amber strobes being on.
5. Test the markers, left and right turn signals, and brake lights.

You cannot overcharge the battery in the light bar, so keep the bar on the charger when not in use. The batteries will resist developing a memory so you do not have to discharge them all the way. However, they must be charged on a regular basis to prevent them discharging to a very low voltage level. When charging, the green LED near the charge port will light.

If you have any issues recharging the battery, plug the cigarette lighter adapter into the vehicle, but not into the light bar. If the LED on the cigarette lighter adapter is not lit, the fuse is most likely blown. Replace the fuse with a 5 amp fuse.

Turn on your wireless light bar before you turn on your monitor kit.

Plug the power jack into the back of the monitor kit, the other end into a 12V power source. Turn on the power switch located on the back panel of the monitor kit. The red LED will light and the alarm will sound momentarily while the monitor kit searches for the signal from the light bar. This will only last a second or two. 

The battery indicator LEDs show your battery strength. All 3 LEDs indicate you have over 12.3V. 2 LEDs indicate you have between 11.3V and 12.3V. 1 LED indicates you have between 10.3V and 11.3V. No LEDs means your battery is below 10.3V and should be charged as soon as possible.

If the red LED on thr right side lights up, a 96db alarm will also sound. This means that your light bar is turned off, is below 3V or has gotten out of range of the monitor kit (possibly left behind or fallen off of the vehicle).

There is an approximate 4 second delay before the light and alarm come on. This is to make sure that some outside interference did not cause a temporary delay in the signal.

1. Check to see if charging plug is receiving power. The charge plug should be connected somewhere so that it receives full time power. Verify voltage with voltmeter. The largest pin on charge plug is GROUND, and the center pin is for power to the light bar.  Check with voltmeter to make sure more than 12v is coming from your vehicle.
2.  Your light bar is equipped with a green charging light, plug your light bar into the charger and verify that the charging light is lit.
3. Check to see if battery leads have come off of the battery terminals.
4. If the charger is a cigarette lighter charger, plug the charger into the power port but not into the light bar. The red LED on the charger should be lit if there is power to the port. If the LED does not light, unscrew the end of the cigarette lighter charge plug and check the 5 amp fuse; replace if it has been blown.
5. Replace the batteries.

1. Make sure that the battery is charged.
2. Check to see if the battery leads have come off of battery terminals or the power switch.
3. Your light bar is equipped with a green charging light, plug your light bar into the charger and verify that the charging light is lit and then re-test the switch.
4. Using a voltmeter, check the voltage of the two outer terminals on the power switch. If the battery is charged or is connected to your charge, the voltage should read 12 volts or more. If it does, turn on the switch and check the voltage of the terminal with the black wire and the center terminal. This should also read 12 volts or more.
5. If it reads 12 volts or more, the LED in the switch is most likely blown. This does not affect the operation of the light bar; it is just an indicator light.
6. If it does not, the switch is bad and needs to be replaced or there is a wire that is not connected between the battery and the switch. Replacement switches can be found at most electronics stores or by calling Custer Products.

1. Custer Products uses the industry standards for wiring our plugs and transmitters. However, many times the wiring on a truck socket does not follow these standards. If this is the case, you should rewire your truck socket. Do not attempt to rewire the transmitter or light bar without approval from Custer Products. Any damage caused by rewiring these items will void the warranty.
2. If your truck has all LED lights, there may be a current load issue. If there is not enough current load on your truck socket, it may trick the transmitter into believing there is voltage being supplied to a pin that is not there. You can add a 560 ohm, ½ watt resistors to each of the signal pins on your wiring (marker, brake, turn signals) and that will add enough loaf to correct the issue. If you are not comfortable doing this, please contact us.
