Javelin 3-Wire to Switch



Light Installation

Javelin Installation

  1. Choose a location on the transom 6 to 12 inches beneath the waterline. The mounting surfaces should be flat, clean, dry, and free of existing hardware or holes. Check inside 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 drill the appropriate hole (0.5"). 
  3. Spread a generous bead of sealant (3M4200 or equivalent) around the inside surface of the light bezel, the screw holes, and the wire stem up to the exposed wire.
  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) into the wire through-hull hole.
  6. On the exterior, tighten the screws hand-tight with a screwdriver (do not use power tools as you may snap the bronze screws).
  7. You should see sealant expelled from around the light housing to ensure adequate bond. Wipe off any access sealant.

3-Wire to Switch 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 underwater light is the light's internal relay and sends commands from the Poco digital lighting control system (if installed).

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 2 or 3 conductor wire from the light to your switch. On a 12vDC system, your switch and fuse should be rated for 7.5A maximum (3A @ 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. 
  • Verify the switch is a Single Pole Single Throw (SPST) switch; it has the appropriate Amp rating and is connected to house power through a properly sized fuse. Recommended switch size for a 3-wire installation is 1A (minimum) switch.
  • Turn on house power and test the new underwater light.

Light Operation

How to Select Color/Mode

STEP 1: First, turn the light on. It will begin in a low-power mode, and over the course of 4 seconds, it will ramp up to full brightness.

STEP 2: After 4 seconds, the light will be at full intensity. The light will initially come on in white and then move into the color cycle mode. The light will now cycle through the complete color spectrum for 15 seconds, followed by a 3-minute color cycle.

STEP 3: When the light reaches the desired color, toggle the power switch off/on one more time to lock on the color. Turning the light off for 4 seconds will reset the color cycle to the beginning.
