Rfroad Lighting 12V Wiring Harness 2-Lead Kit for Two LED Lights — 40A Relay & Illuminated Switch

Rfroad Lighting 2-lead wiring harness kit connects two 12V LED lights with a durable nylon sleeve, reliable 40A relay, 30A fuse, and illuminated rocker switch for safe, plug-and-play installation.

This wiring harness is built to power a pair of LED devices—light bars, pod lights, fog lights or rock lights—directly from a 12V vehicle battery. The assembly uses heat-resistant nylon insulation instead of PVC for improved durability, includes a heavy-duty 40A relay and 30A blade fuse for circuit protection, and provides an illuminated 3-pin rocker switch so you can operate lights easily at night. At 8.2 feet long, the harness gives flexible routing options for trucks, UTVs, ATVs, and boats.

How does the harness protect my vehicle's electrical system?

The kit adds both active and passive protection to the lighting circuit to reduce the risk of overload and short circuits. A 40A automotive relay isolates the switch from the high-current path, while a 30A blade fuse provides sacrificial overload protection.

• 40A relay prevents switch overheating and wiring stress
• 30A blade fuse protects against short-circuits and overcurrent
• Inline connector points simplify troubleshooting and replacement

What makes the nylon sleeve better than PVC for an off-road harness?

Nylon-jacketed wiring resists high temperatures, abrasion, and moisture better than standard PVC, which matters when wiring is exposed to engine heat, road debris, or rough trails. The nylon jacket improves longevity and helps keep electrical contacts dry and dust-free.

• High temperature tolerance for under-hood routing
• Improved abrasion resistance for frame and engine bay contact
• Waterproof and dustproof properties for outdoor use

How do I install this kit in my truck, UTV, or boat?

Installation is straightforward for anyone familiar with basic 12V wiring: run the harness from the battery to the lights, secure the relay near the battery, mount the switch inside reach, and attach the fuse. The kit includes long leads to reach common mounting points without splicing.

• Mount relay close to the battery for stable power feed
• Run the 8.2 ft harness to avoid tight bends or stress points
• Use included connectors for a secure, serviceable connection

Will this harness work with my specific LED lights and load?

The harness is engineered for a combined 12V load up to 300W, making it suitable for most paired LED pods and mid-size light bars. Check your lights' combined wattage to confirm compatibility and avoid exceeding the 30A fuse or 40A relay rating.

• Supports up to 300W total at 12V without modification
• Designed for two LED devices wired in parallel
• Replace fuse or relay if you upgrade to higher current units

Who is this for: This Rfroad Lighting harness is intended for vehicle owners, mechanics, and DIY installers who want a dependable, ready-to-use solution to power two 12V LED lights. It's especially useful for off-road enthusiasts, truck owners, UTV/ATV riders, and boat operators seeking a rugged, temperature-resistant wiring kit with clear switch control and built-in safety protection. If you need a straightforward harness with long leads, nylon insulation, and reliable circuit protection, this kit simplifies the job and supports common LED lighting setups.
