LASFIT 10ft 12AWG Wiring Harness Kit for LED Light Bars – 12V Heavy‑Duty, ON/OFF Switch & Inline Fuse

The LASFIT 10ft 12AWG wiring harness kit is a heavy-duty, plug-and-play power loom designed to safely run LED light bars and pods on 12V vehicles.

This wiring harness bundles a durable 12AWG power lead, replaceable relay, blade fuse, and an ON/OFF switch inside a waterproof PVC jacket so you can mount auxiliary lighting quickly and reliably. Built for off-road and street use, the harness provides extended length and multiple safety features so installers can focus on positioning lights rather than wiring headaches.

How easy is the harness to install?

Installation is straightforward for anyone with basic electrical experience: route the 10-foot lead from the switch to the light, ground the black wire, and connect the fused power to the battery. The plug-and-play layout reduces splicing, and labeled connections speed up setup.

• 10 ft total length from switch to light for flexible mounting
• Pre-terminated connectors for quick attachment to lamps
• Inline blade fuse and replaceable relay already integrated
• Simple ground and battery power connections; minimal tools required

What safety features protect my electrical system?

This kit includes multiple protections to minimize risk of short circuits and overcurrent. The inline blade fuse is the first line of defense, while a sealed relay and quality terminals ensure reliable conductivity under vibration and moisture exposure.

• Inline blade fuse guards against overcurrent and wiring faults
• Sealed, replaceable relay reduces heat and contact failure
• PVC-wrapped wiring and rubber-protected relay offer water resistance
• High-quality pins and connectors improve long-term electrical contact

• Universal 12AWG gauge suitable for most auxiliary LED loads
