Each socket includes a built‑in fuse holder and heavy 14AWG main conductors, so you get protected high-current switching without needing separate fuse blocks. The plug‑and‑play wiring and interlocking socket design reduce installation time and keep wiring tidy in tight spaces.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these relays make wiring automotive accessories easier?\u003c\/h3\u003e\n\u003cp\u003ePre-labeled, color-coded wires on every socket let you identify ground, power, trigger and switched output at a glance, cutting guesswork during installation. The harnesses use thicker 14AWG conductors for the main current path, so you can run lights, motors or locks with greater confidence.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eColor-coded leads: Black = ground (85), Red = battery power (30), White = trigger (86), Blue = normally open output (87)\u003c\/li\u003e\n  \u003cli\u003e14AWG heavy-duty wires for main contact to handle high current\u003c\/li\u003e\n  \u003cli\u003ePlug-in sockets for quick swap or service without rewiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat safety features protect the circuits?\u003c\/h3\u003e\n\u003cp\u003eEach relay socket includes an onboard blade-fuse slot populated with a 30A fuse, so the switched circuit is protected right at the relay.

It’s also useful for fleet or shop technicians who prefer pre-wired, fused relay solutions that reduce installation time and improve serviceability.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are the fuses included with the Nilight relay kit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
