Underdeck Pontoon Light Installation Instructions

Your under-deck pontoon boat light kit contains:

• 2 19.7' pre-cut under deck strip lights

• 1 underdeck light harness

• 10 4’ sections of mounting strip with 3M adhesive tape

The under-deck pontoon strip lights will install in four easy steps.

Step 1 – Mounting strip installation

The best location to install your under-deck lights will be on the bottom of your pontoon deck with the light facing down. Lay out half of your mounting channel on each side of your boat. Measure your lights for their exact length and cut your installation channel to match. There is enough mounting channel to provide a continuous mounting surface for your underdeck lights. Center the lights on each side of your boat and remove the backing of the 3M adhesive strips and stick under your deck.  If necessary you can use screws to secure the channel. 

In all cases, we recommend installing the lights so they reflect off of the water and your pontoon tubes. We do not recommend installing the lights so they can be seen in direct view from another boat.

Step 2 - Installing the Under-Deck Pontoon Lights

In most cases, it is easier to make the electrical connection to your underdeck lights at the stern of the boat. Starting at the bow end of your mounting channel, remove the double-sided tape backing and begin snapping the underdeck lights into place. Continue to the stern. Repeat on the other side of your boat. The design of the wire harness will allow you to run the lights in either direction or one in each direction. Once the lights are installed, apply a generous amount of silicon at each end of both lights to add extra waterproofing and strain relief for the wires.

Step 3 – Wire Harness Routing

Your underdeck wiring harness is shaped like a large letter “V”. The base of the V connects to your helm wiring. The tips of the V plug directly into the plugs on the ends of your underdeck lights. IMPORTANT: One of the leads on your underdeck harness is longer than the other. Use this one for your port side light.

Route your underdeck wiring harness along the top of your pontoon with other boat wiring. Run across the width of your pontoon boat with other wiring and a cross channel. Secure your underdeck wiring at least every 18”. Make sure the harness will not become snagged by a trailer or other obstacles that travel under your boat.

Step 4 – Connecting your Harness to the Helm

Your underdeck wiring harness comes with piggy back quick connect terminals designed to easily connect to most accessory switches.

Positive Connection

If your underdeck lights are being controlled by their own switch, simply connect the blue wire from your underdeck light harness to the open terminal on your switch.

NOTE: The orange/white wire on the switch above is the power wire for the switch. The black wire is the ground for the light in the switch.

If your underdeck lights are being controlled by a switch that also controls another function, remove the switched power wire from the switch and connect it to the piggy back terminal on the blue power wire from your underdeck light harness. Re-install the blue combo of wires back onto the switch.

NOTE: The orange/white wire on the switch above is the power wire for the switch. The red wire on the switch is connected to the existing component controlled by this switch. The black wire is the ground for the light in the switch.

Ground Connection

Remove the black wire from the switch and connect it to the piggy back terminal on the ground for your underdeck light harness. Re-install the black wire combo back onto the switch.

Please ensure that the switch has at max a 10 amp fuse or circuit breaker.
