Which Lights Work With the Building Block Wire Harness?
One of the most common questions we get is:
“Which lights work with the Building Block Wire Harness?”
This guide answers that clearly and completely.
The Building Block Wire Harness was developed to eliminate permanent wiring, soldered harnesses, and inflexible setups. It allows anglers and hunters to power and control multiple lights using plug-and-play, waterproof components—and to reconfigure those lights on the fly as conditions change.
Below is the complete, current compatibility list, broken down by how each light interfaces with the system.
What the Building Block Wire Harness Actually Does
- The Building Block Wire Harness allows you to:
- Power multiple lights from a single power source
- Control multiple lights from one or more control dials
- Split lights into zones (left / right / front / back)
- Reconfigure control layouts without rewiring or soldering
- Add or remove lights without rebuilding the harness
Not every light uses both power and control leads—and that distinction matters. That’s why compatibility is broken into two categories below.
Lights Compatible With Power AND Control Leads
These lights fully integrate into the Building Block Wire Harness system and support both power distribution and control via control dials.
They can be zoned, split, regrouped, and adjusted on the fly.
- Swamp Eye® HD Bowfishing Light
- Swamp Eye® Silent Series Bowfishing Light
- Swamp Eye® Gen 2.X Light Bar
- Predator Cannon® Flood Series Hunting Light Bar
- 40 Inch Hunting Series LED Light Bar (Red / White)
See our complete building block wire harness guide
What this means
- These lights can:
- Share power leads
- Share or split control dials
- Be grouped or ungrouped instantly
- Be tuned independently for color and brightness (where applicable)
Lights Compatible With Power Side Only
These lights integrate into the Building Block Wire Harness for power distribution only and do not use control leads.
They are designed for fixed-output operation and benefit from the same modular, plug-and-play wiring system.
- DURANAV® Marine Grade Driving Light
- DURANAV® Duck Boat Light
- DURANAV® Duck Boat Light Kits
- Underwater Green Fishing Light
- Above Water Green Fishing Flood Light
- Predator Cannon® Hunting Light Bar (2026 and later models)
See our complete building block wire harness guide
What this means
These lights:
- Plug directly into Building Block power components
- Do not use control dials
- Are ideal for trunk line power distribution
- Benefit from clean installs and easy expansion
Building Block Wire Harness Compatible Components
The system is made up of modular components that fall into two main categories. For more information - see our complete building block wire harness guide.
Control & Individual Power Components
Used when lights require individual power and/or active control.
Controllers
Control Cables
Power Cables
These components are most commonly used with Swamp Eye Lights and hunting light bars that require real-time control.
Trunk Line Power Components
Used to build shared power trunk lines that feed multiple lights from a single source.
- Tee Connector for Power Cord Trunk Line
- Power Cord Trunk Line Lead
- Transition Lead – Trunk Line Plug to Individual Light Plug (supports up to 30 amps)
- Power Cord Lead with Trunk Line Battery Terminals
- Power Cord Junction Hook Up for Trunk Line
- Power Trunk Line Plug and Play Wiring Kit
- These are most commonly used for:
- Boats set up for flounder gigging, bowfishing, bully netting, or duck hunting
- Dock lighting systems
- Underwater green fishing lights
- Large multi-light boat setups
- Fixed-output lighting systems
Power Trunk Line Plug-and-Play Wiring Kits
For customers who want a pre-configured solution, we also offer Power Trunk Line Plug-and-Play Wiring Kits.
These kits bundle the most commonly needed trunk line components together and are ideal for:
- Boats set up for flounder gigging, bowfishing, bully netting, or duck hunting
- Dock lighting installations
- Underwater green fishing lights
- Large multi-light or permanent setups
Why This System Exists (And Why It Matters)
Before the Building Block Wire Harness, customers often requested permanently soldered harnesses so multiple lights could be controlled by one dial.
That created problems:
- Layouts were permanent
- Changes required shipping harnesses back
- Customers couldn’t adapt to changing water or hunting conditions
The Building Block Wire Harness solved that.
Now, you can:
- Control 6 lights on one dial tonight
- Split them into two zones tomorrow
- Adjust color balance side-to-side based on water clarity
- Expand or reduce your system without rewiring
All using waterproof, plug-and-play components.
Final Takeaway
If a light is listed above, it is officially compatible with the Building Block Wire Harness—either for:
- Full power + control integration, or
- Power-side distribution only
If you’re unsure which components you need:
- Determine whether your light requires control
- Decide whether you want individual power leads or a trunk line
- Or contact us and we’ll size it correctly the first time
The Building Block Wire Harness was built to give you flexibility without compromise—and it will continue to expand as new lights are released.
