Lite-it-Wireless 48″ LED Light Bar With Flashers

  • 48″ Wide
  • Auto delay flasher that turns off when a turn signal or brake is applied
  • Rubber trap mounting plus ratcheting straps
  • 7 pin connection


The LIW-48RFS-7 wireless tow light system comes with a light bar, transmitter and a charge cord. The flashers are activated when you turn on the light bar. When either the turn signals or brakes are activated, the flashers stop until the turn signals or brake lights are inactive for 1 second. Then they resume until the next event. No more confusion for the drivers behind you. They will know your intentions instead of being confused by the flashers. Simply plug the seven pin transmitter into your trucks seven pin connector. Turn on the truck bar by switching the on/off button. The taillights do not come on when the unit is powered on, only when the towing vehicles taillights are on. This is a tremendous battery saver.

Light bars feature all L.E.D. lights, transmits up to 1000ft. If you forget to charge the bar, just plug in your 7 pin cable to run as a cabled unit. We offer a 3-year warranty on the circuit boards.

  1. Plug the transmitter into your vehicles 7 pin connector
  2. Turn on the power switch located between the lights on the left side of the light bar. The red LED on the switch will illuminate when it is on.
  3. 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.
  4. Test the markers, left and right turn signals, and brake lights.
  5. The amber flashers turn on when the power switch located between the (2) 4 red lights on the left side of the bar is turned on and the switch located underneath the 2 center markers is turned on. They will flash alternately. When the brake lights or turn signals are activated they will stop flashing until the brake or turn signal is not active for 1 seconds.
  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 7 pin cable into the charging socket on the left side of the bar and operate it just like one of our wired bars. If the center pin on your truck socket is a 12v source, this will also charge the light bar.

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.

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.
