Light Installation

Typhoon Installation

  1. Choose a location on the transom 6 to 12 inches beneath the waterline. Mounting surfaces should be flat, clean, dry, and free of any existing hardware or holes. Check inside of the hull for wiring or obstructions.
  2. Before mounting, ensure that the light will not interfere with the operation of engines, trim tabs, rudders, etc. Clean the gelcoat or remove any bottom paint from the gelcoat surface. Mark the light center and cut the appropriate hole for your housing type. Refer to the instructions for the recommended hole saw size.
  3. Spread a generous bead of sealant (3M4200 or equivalent) around the inside surface of the light bezel. 
  4. Feed the light housing through the hole and orientate using the logo on the reflector. Fasten in place with tape.
  5. On the inside of the hull, apply a generous bead of sealant (M4200 or equivalent) to one surface of the stainless steel washer and feed the washer over the threads of the light with the sealant side making contact with the hull.
  6. Thread the Compression Nut Retaining Ring onto the light housing threads and fasten until approximately one inch from the steel washer.
  7. Install the three supplied retaining bolts to the Compression Nut Ring until they make contact with the steel washer surface (hand-tight). Tighten with a socket wrench until sealant extrudes from behind the washer. DO NOT over-tighten.
  8. Install the Bonding Lug with supplied nut and both, and clean off any access sealant for the front and rear of the light.

3-Wire to Poco Wiring 

Wiring recommendations: Use ABYC standards to calculate wire size based on the length of the run. If installed as a 3-Wire configuration, the orange wire carries less than 1A of power, and typically, an 18AWG wire can be used. The orange wire of the Typhoon light is the internal relay of the light and is also the wire that sends commands from Poco.

TIP: To minimize electrical noise and interference, running the positive (red) power and ground (black) return together for as much of the wire run as possible, ideally inside a jacketed cable, is recommended. Avoid loops and coils of the wiring.

  • Ensure that the circuit you are connecting to has no power. You should turn off your house battery and test to ensure the circuit is not energized by using a multimeter before continuing.
  • Run a marine grade 3 conductor wire from the light to your switch and power source. The red wire will connect to constant power after the house power kill switch, the black to common ground, and the orange wire to the normally open side of a switch. You should install a 15A fuse on the red wire on a 12vDC system (7.4A @ 24vDC).  View wire gauge reference chart HERE.
  • Connect the wires from the light to the new wire run and follow ABYC standards. Ensure that the wires are crimped correctly, and use a heat gun on the heat shrink of the butt splice connectors. 
  • Turn on house power and test the new Typhoon underwater light.

Light Setup in Poco

Add Your Typhoon Light to Poco

You will need to configure Poco to add the Typhoon to the light group, switch, and layout pages of Poco.

Start by connecting to Poco and going to the Configuration setup (Gear wheel in the top right of the screen). The passcode is “0000”


  • Under Light Groups, add a new light Group called LG Typhoon.
  • Select the Poco channel output you connected the Typhoon Orange wire to.
  • Select Clan 4 for the Underwater Lights.
  • Select Spectrum RGBW as the Output.
  • Save the Light Group


  • Go to the Switches Menu.
  • Add a Switch.
  • Switch name is what will appear on the App and or MFD.
  • Leave Widget type as Omnillume.
  • Click on the box below Target and select the LG Typhoon you created in the previous step.
  • The default intensity is set to 100%. If you would like to change this, click on the 100% and select a value between 10% and 100%.
  • Click Save


  • Go to the Layouts Menu.
  • Click the Add Switch to the layout by clicking on the Plus (+) sign in the dotted circle and select the Switch you just created.
  • Select the Home button icon (house) on the top right of the screen to return to the home screen.
  • You will now see the button you created

If you press and hold the Switch, you will see the Omnillume screen. From here, you can turn the light on and off, change color or increase or decrease the light brightness.
