Nilight Light Bar Wiring Harness Kit 16AWG — 5‑Pin Backlit Rocker Switch, Dual‑Output 12V/180W

Nilight's 16AWG 2-leads light bar wiring harness kit with a 5‑pin LED rocker switch delivers a ready-to-install, 12V wiring solution for powering up to 180W of LED light bars safely and cleanly.

This harness pairs a sturdy 16AWG cable, a power relay with blade-fuse protection, and a backlit 5‑pin SPST rocker switch so you can control one or two LED fixtures from a single, neat wiring bundle. The kit is designed for quick installation on 12V vehicles — from jeeps and trucks to ATVs, UTVs, motorcycles, boats, and trailers — and includes two output leads so you can run dual lights without adding extra wiring complexity. Two spare fuses and an instruction sheet are included to simplify setup and maintenance.

How does this harness keep my lights and vehicle safe?

The harness uses a separate power relay to handle high current and a blade fuse to interrupt overcurrent or short-circuit conditions before damage occurs. The relay reduces load on the switch, while the included spare fuses make replacement straightforward in the field. Together they help prevent wiring overheating and protect both your light bar and vehicle electrical system.

• Integrated power relay to isolate high-current draw from the switch.
• Blade fuse holder with installed fuse plus two spare fuses for quick swaps.
• 16AWG cable rating suitable for up to 180W total load on 12V systems.

Can I use this kit for two light bars or large single bars?

Yes — the harness provides two output leads so you can connect dual lights or one larger fixture as long as the combined load does not exceed 180W at 12V. The dual-output design keeps wiring tidy and avoids the need for separate runs from the battery. If you plan to exceed 180W or use a 24V system, swap in a suitable relay and confirm cable ratings before proceeding.

• Two light output connectors for pairing dual fixtures without extra harnesses.
• Maximum recommended load: 180W on a 12V system (verify total wattage).
• For 24V systems, replace the included 12V relay with a 24V relay.

What makes the Nilight 5-pin rocker switch user-friendly?

The included 5‑pin SPST rocker switch features built-in LEDs that emit a soft glow, helping you locate the control in low light. The SPST design provides a simple on/off action for straightforward operation, and the switch mounts cleanly in standard panels or dash openings. Wiring is simplified by clear connector placement and the kit’s instruction sheet.

• Backlit rocker with two premium LEDs for low-light visibility.
• SPST on/off functionality for uncomplicated control.
• Compact form factor suitable for common dash or panel cutouts.

How difficult is installation and what comes in the box?

Installation is designed for hobbyists and installers comfortable working with vehicle electrical systems; the harness arrives pre-assembled with a fuse holder, relay, switch and two output leads. Mount the switch, route the 12-foot lead to your battery, connect outputs to your light bar(s), and secure grounds as instructed. If you are unsure, consult a qualified auto electrician.

• Kit includes: wiring harness, 5‑pin LED rocker switch, instruction manual, and two spare fuses.
• 12-foot extendable main lead for flexible routing to battery and lights.
• Pre-terminated connectors speed up installation and reduce wiring mistakes.

Who is this for: The Nilight 16AWG 2-leads wiring harness kit is built for vehicle owners and installers who want a reliable, protected, and easy-to-install control solution for 12V LED light bars up to 180W. It suits off-road enthusiasts wiring dual light bars on jeeps and trucks, boat owners adding deck lighting, and anyone who prefers a tidy, fused, relay-driven harness with a backlit switch for nighttime use. If you need a higher wattage or a 24V-ready setup, choose appropriately rated components or a relay replacement before installation.
