Is your light bar draining your battery?

There are many reasons why your newly installed light bar might be draining your battery, we suggest you do the following checks:

  • Connect your light bar directly to the vehicle battery or another DC voltage source. If you going to use a power supply, make sure its voltage output is within the light bar’s specifications. Also, make sure it can supply the maximum current your light bar draws.
  •  Use a wire gauge that matches or exceeds the maximum current of your LED light bar.
  •  Fuse power wires to the expected current draw, not the wire size.
  • Use an automotive switching relay if the light bar draws 10A or greater.
  • With or without a relay, use a cab switch rated for at least 10 amps.
  • Secure the relay to a suitable location, and test the light to make sure the circuit works.
  • Use waterproof wiring connectors. Check for these at a local marine shop.
  • Avoid unnecessary splices, but use a snap-in connector at the light bar to ease removal.
