Wiring the Takedown or Worklights (LGD24 or LGD32 Models Only)

The light bar's worklights are a factory-configured option. The light bar is shipped
with the option's three-conductor cable ready for splicing into the vehicle harness.
For the location of the lights, see Figure 3 on page 25.
BATTERY EXPLOSION: To avoid a battery explosion, always disconnect
the negative battery cable first and reconnect it last. Avoid causing a spark
when connecting near or to the battery. The gases produced by a battery
can cause a battery explosion that could result in vehicle damage and
serious injury.
To wire the takedown lights or worklights:
1. Disconnect the vehicle battery's negative ground cable, and then the positive
cable.
2. Locate the three-conductor cable exiting the light bar with red, black, and green
wires.
3. Connect the wires to switched 12 Vdc positive signals to activate. See Figure 11.

FROM LIGHT BAR
NOTE: High Power Mode overrides the Low Power Mode. If both lines are
activated, the worklights come on in High Power Mode. Low Power Mode dims
the light bar to 50 percent of full brightness.
4. Reconnect the battery's positive terminal, and then the negative terminal.
5. Test the light bar to verify that it operates properly.

Wiring for 12-inch Legend

The 12-inch Legend model is available with either an internal flasher that randomly
flashes the two light heads, or an external flasher that simultaneously flashes the
two light heads.
