Rfroad Lighting 12V 2-Lead Wiring Harness for LED Light Bars and Fog Lights — 11.4ft Nylon, 40A Relay, Illuminated Rocker Switch

Rfroad Lighting 2-lead wiring harness is a complete 12V kit built to power a pair of LED light bars or pods with a 40A relay, inline fuse and illuminated rocker switch for safe, reliable control.

This wiring harness kit gives you everything needed to install and control two LED devices on vehicles, UTVs, ATVs, boats or trailers. The 11.4 ft nylon-jacketed cables, 40A relay and 30A fuse provide long run length and circuit protection, while the five-pin illuminated rocker switch and fully insulated connectors simplify installation and nighttime operation. The kit supports a combined load up to 300W on a standard 12V system and is compatible with light bars from 2" to 52" and a wide range of pods and fog lamps.

How straightforward is installation for a DIY mechanic?

Installation is designed to be plug-and-play for users comfortable with basic vehicle wiring. The harness includes pre-crimped male and female connectors, a relay socket, inline fuse holder and a labeled rocker switch so you can route wires, secure grounds and connect power without fabricating adapters.

• 11.4 ft cable length for flexible mounting locations
• Pre-terminated connectors reduce soldering or splice work
• Heat shrink tubes included for sealed wire joints
• Clear relay, fuse and switch attachments for quick wiring

What protections keep the circuit safe and reliable?

The harness uses a 40A automotive relay and a 30A blade fuse to limit overcurrent and help prevent damage from short circuits. A nylon outer jacket enhances thermal durability and abrasion resistance compared with basic PVC, and the inline rubber-capped fuse makes fuse access and replacement simple.

• 40A relay for controlled switching and longer component life
• 30A blade fuse for primary overcurrent protection
• Nylon jacket resists heat and chafing in engine bays or off-road use
• Rubber cap protects fuse from moisture and debris

Will this harness work with my light combination and vehicle type?

The kit is universal for 12V systems and supports a combined load capacity suitable for most LED light bars, pods and fog lights up to roughly 300W total. Whether you have a compact 2" pod or a full-length 52" light bar, the two-lead design lets you run a pair of lights or dual circuits from one switch and relay assembly.

• Compatible with 2"–52" light bars and many LED pods
• Suitable for trucks, UTVs, ATVs, SUVs, boats and trailers
• Two-lead layout for paired lights or two separate fixtures
• Works on standard 12V electrical systems

How durable are the switch and connectors for outdoor use?

The kit includes a five-pin illuminated rocker switch rated for many cycles and fully insulated connectors to resist corrosion and accidental shorts. The switch illumination makes it easy to find at night, and included heat shrink tubing helps seal terminations against water intrusion.

• Illuminated 5-pin rocker switch for nighttime visibility
• Switch tested for more than 10,000 presses for longevity
• Fully insulated male/female connectors reduce risk of accidental contact
• Heat shrink tubes included for weatherproof connections

Who this kit is for: Rfroad Lighting's 2-lead wiring harness is aimed at DIY installers, fleet technicians and off-road enthusiasts who need a ready-made, protected wiring solution for powering two LED fixtures on a 12V system. It's a practical choice if you want a durable nylon jacket, clear circuit protection with a relay and fuse, and an illuminated switch for easy control—without splicing together separate parts from multiple suppliers.
