Nilight 3-Gang 12V Rocker Switch Panel Wiring Harness Kit — 9.8ft, LED Indicators, 540W Relay Protection

This wiring harness kit is built for vehicle and marine accessory projects where reliability, neat installation and clear control matter. With a 16AWG stranded main, relay protection and blade fuses included, the kit is designed to power multiple LED light bars, auxiliary lamps or other 12V accessories while keeping wiring organized and protected. The panel’s illuminated rocker switches are rated for thousands of presses and accept DIY labels so you can identify each circuit at a glance.

How much power can this harness handle and how is it protected?

The Nilight harness supports a total load of up to 540W at 12V thanks to its 16AWG stranded wiring and relay design. Each of the three switches manages an individual circuit with up to 180W capacity, and protection is provided by an inline blade fuse and a power relay acting as primary overcurrent defenses.

• 16AWG stranded wire for flexible routing and heat tolerance.
• Up to 540W total load; 180W per switch circuit.
• Includes power relay to reduce switch wear and prevent voltage drops.
• Inline blade fuse protects against short circuits and overloads.

What components are included and how long is the harness?

The kit ships as a ready-to-install set with a three-gang switch panel, wiring harness, fuses, spade connectors and installation instructions. The full harness measures about 9.8 feet, long enough for most engine bays and dashboard runs—confirm your mounting points before purchase to ensure fit.

• 3-gang rocker switch panel with blue indicator LEDs.
• Complete wiring harness totaling 9.8 ft for routing to lights and battery.
• Blade fuses and spade connectors included for a clean install.
• Printed instructions to guide wiring and optional LED wiring arrangement.

How many lights or accessories can I control and where can I use this kit?

Each switch controls an individual circuit with two output leads, so the three-switch panel provides six output leads in total—enough to run multiple lights in different vehicle zones. The harness is compatible with most 12V systems: cars, trucks, SUVs, ATVs, UTVs, motorcycles, campers, boats and trailers; for 24V systems use a 24V relay instead.

• Six output leads let you wire pairs of lights or accessories to separate switches.
• Suitable across automotive, marine and powersports 12V applications.
• Switch LEDs show status; wiring can be rearranged for LED-on-only-when-ON operation.
• Replace relay for 24V systems—do not use as-is on 24V vehicles.

Who is this for: The Nilight 3-gang rocker switch wiring harness is ideal for DIY mechanics, shop installers and outdoors enthusiasts who want a tidy dashboard control solution for multiple 12V lights or accessories. It’s a good match for anyone fitting light bars, fog lights, interior rigs or auxiliary devices who needs relay protection, inline fusing and clear switch labeling. If you need very long runs or higher-than-540W aggregate loads, plan alternate wiring or higher-gauge wiring and proper relays before installation.
