Nilight 16AWG LED Light Bar Wiring Harness 4-Lead — 2-Gang Rocker Panel, 180W per Circuit

Nilight's 16AWG 4-lead wiring harness is a ready-to-install electrical kit that powers and controls up to four 12V LED light circuits via a 2-gang rocker switch with built-in relays and fuses.

Designed for vehicle lighting projects, this harness packages heavy-duty wiring, a dual-switch panel, and protective components so you can add multiple LED bars or auxiliary lights without custom splicing. The kit simplifies routing, protects circuits with inline fuses and relays, and offers an attractive two-switch control with illuminated indicators for clear on/off status.

How much load can each circuit handle and how is the harness protected?

Each of the two switch-controlled circuits supports up to 180W, giving the harness a combined capacity of 360W when both circuits are used within their limits. Protection comes from an automotive-grade power relay plus inline blade fuses positioned as the primary defense against overcurrent and short circuits.

• 16AWG stranded wire rated for heavy-duty use and reliable current flow.
• 180W per circuit; 360W total capacity when both circuits are balanced.
• Power relay reduces switch load and extends component life.
• Inline blade fuses protect wiring and lights from faults.

Can I run four lights independently and how are the switches configured?

The harness provides four output leads grouped across a 2-gang rocker switch panel, so each rocker controls a pair of leads or a separate circuit depending on your wiring layout. The panel includes blue illumination when a switch is engaged and features laser-etched markings built to resist wear.

• Two rocker switches for flexible on/off control of front and rear lighting or other groupings.
• Blue indicator LEDs show active circuits for quick visual confirmation.
• Laser-etched pattern on switches for durable labeling and long life.
• Switches tested for thousands of cycles for reliable operation.

What vehicle types and voltages is this harness compatible with?

Out of the box, the harness is built for 12V systems common in cars, trucks, ATVs, UTVs, motorcycles, RVs, boats and trailers. If you operate a 24V electrical system, swap the supplied 12V relay for a 24V-rated relay to maintain correct operation and component safety.

• Compatible with most 12V battery vehicles and marine craft.
• Simple relay replacement enables 24V system adaptation.
• Connectors and blade fuses included to speed installation.
• Compact switch panel fits dashboards, consoles, or mounting plates.

What does the kit include and what additional parts might I need?

The package supplies a fully assembled 2-gang wiring harness with four output leads, blade fuses and spade connectors so you can begin installation immediately. Depending on your install location, you may need mounting screws, heat shrink, cable ties, or ring terminals to attach to your battery and light fixtures.

• Included: 2-gang wiring harness, blade fuses, spade connectors for quick wiring.
• Recommended additional items: ring terminals, zip ties, terminal crimper, and routing hardware.
• Consider weatherproofing or conduit for exposed runs in off-road or marine use.

Who this is for: Installers, hobbyists, and vehicle owners who want a reliable, plug-and-play solution for powering multiple LED light bars or auxiliary lights. The harness is ideal if you need a compact control panel, circuit protection, and the ability to manage front/rear or grouped lighting independently without building a wiring loom from scratch.
