NOTES ON INSTALLING AND USING YOUR NEW TOWER LIGHTS
Tower lights will reach a high temperature when operating. Do not touch or wash the
lights for 10 minutes after use.
Only use “H3 55W 12V” Halogen light bulb and fuse for replacement. These are available
online at bulbs.com and most auto parts stores. Anything exceeding 55W/15Amp could
result in damage to your boat wiring.
Use appropriate gauge wire for all connections. Consult wiring diagrams & wire sizing
chart for details.
Use of a relay is highly recommended unless you confirm your switch can support a 20
amp load. An inline fuse is required (see wiring diagram)
Tower lights are not for wakeboarding at night, which is illegal in every state.
There are countless methods of wiring lights. Please contact a marine wiring specialist if
you need assistance. We have provided the most complete information we have found
within this document.
It is highly recommended that you use a relay and a fuse with each set of lights.

Attaching the light bar to the tower
Attach the Collar Bracket (Item 1) to the tower using M8x25 bolts (Item 4) and the Collar Inserts
(Item 2) that matches your size tower (2-1/2” are provided for Monster Towers and a universal kit
with 1-1/2”, 1-5/8”, 1-3/4”, 1-7/8”, 2” and 2-1/4” are provided for other towers).
Turning the lights to all face the same direction
You can easily turn the outside lights so all four lights face in the same direction.
1) Remove Light Bolts on each end of the light
2) Remove End Cap
3) Remove Bracket Bolts to remove the bracket
4) Remove threaded bar and insert into the opposite railing
5) Re-assemble and align the center hole of the bracket where the wire exits the tube
IMPORTANT – Tighten bracket bolts BY HAND, then 1⁄4 of a turn ONLY or the

Wiring Recommendations
We recommend using a SPST relay (Single Pole Single Throw) with your switch and appropriate
gauge wiring. Relays are readily available at auto parts stores, Radio Shack, and online at
www.PartsExpress.com (part number 330-070) and cost under $5 each. Parts Express also has an
excellent technical support department. There are many sources and links for wiring 12V lights at
www.diyTower.com that you may want to reference.
Not using a relay could cause excessive heat in the wiring and switch and create a risk of fire
because of the amount of power being drawn by the high output lights. A relay works by using a
switch to run 12 volts to the relay. The relay acts as an electrical switch that activates and draws
power straight from the battery connection and sends it to the lights or accessory. The power
actually going to the switch never gets routed to the lights.
See diagrams and wiring size chart at the end of this document for options & details.
Running Wires Through The Tower
The following is specific to running wires on a Monster Tower, otherwise consult your tower
installation manual or provider for instructions on running wire inside your tower.
When you add speakers or lights to your Monster Tower, you can hide the wires inside of the rear
legs of the tower as well as in the straight cross member of the top section. Since the mating
parts insert 1⁄2” inside each end of the rear leg you can drill 1” away from the weld lines. For the
top section cross member you will need to place the hole 3” from the weld line to clear the
rotating collar assembly. The hole size will depend on what size wire you are running and how
many items you need to wire. The maximum hole size we recommend is 1⁄2” but normally smaller
is all that is needed.
We recommend covering the exposed wiring with 3/8” or 1/2” wiring loom and electrical tape for a
professional, watertight appearance.
