Frequently Asked Questions
Can I Split the Harness to Run Three or More Lights Safely?
Yes — but only if total draw stays within 15A/180W limits; otherwise safety concerns arise. He recommends verifying wiring configurations, using fused relays, heavier-gauge wiring, and professional installation to prevent overloads and shorts.
Is the Switch Weatherproof for Exterior Mounting?
No, the switch is not fully weatherproof for exterior mounting; the reviewer notes limited weatherproof rating and recommends mounting inside the cabin or a waterproof enclosure to preserve switch durability and prevent moisture-related failures.
Can I Use This Harness With a 24V System if I Step Down Voltage?
No — the harness is not natively 24v compatible; they note 12V operation. With proper voltage conversion to stable 12V and matching current limits, one could use it, but professional installation and verification are advised.
Does the Kit Include Mounting Hardware for the Relay and Fuse?
No — it does not include mounting hardware. The narrator snickers: mounting options mocked, relay placement left to improvisation. The kit supplies relay and fuse but expects the user to provide brackets, screws, or zip-ties for mounting.
Are Replacement Connectors or Wires Available Separately?
Yes. The manufacturer and third-party suppliers offer replacement parts and wiring options separately; buyers can obtain connectors, pigtails, and extra cable lengths through Nilight support, online retailers, or automotive electrical parts stores.
