NOTES
You may need to provide wire for your tower and boat. You will need two fuses for the interior boat wiring. You
will need wire for both the lights and the LED interior light – enough length to run to your desired power source
or switch (depending on your install).
We recommend a minimum 18 gauge wire for powering both the lights and the interior LED. You must mount
an in-line fuse on the positive wire of each circuit between your battery and the switch. The in-line fuse is
designed to protect your wires and the lightbar in case of short circuit. We recommend using a 5 amp fuse.
MOUNTING OPTIONS
Your new NV4 Light Bar can be mounted anywhere on your tower – it has been designed to have the interior
LED facing down but can be mounted to face upward. The lights will rotate to face either direction so it’s up to
you to choose a suitable mounting location.
Both ends of the light bar are equipped with a speakon connector, however only one end needs to be plugged
in. This allows you to connect multiple lightbars on the tower without running a dedicated circuit for each.

Hold the bar in the position you would like on your
tower (see recommendations for mounting options at
the beginning of these instructions).
Verify which of the 2 mounting positions will work best
for the location you have chosen.
Replace the rubber plugs in the extra holes you will
not use and attach the clamps to the holes that will be
used. (See Step B)
