Nilight 50023R 5-Pack 30A Fused Relay Kit | 12V 4-Pin SPST with Interlocking Harness

Overview

The Nilight 50023R 5-Pack 30A Fused Relay Kit delivers a compact, ready-to-use solution for 12V automotive electrical projects. Each relay includes a built-in fuse socket and heavy-duty wiring, eliminating the need for a separate fuse holder and helping to maximize space in crowded engine bays or dash areas. The kit pairs five durable 30A blade fuses with robust 14 AWG conductors, designed to handle power-dense tasks while keeping wiring tidy and protected.

Clean, space-saving design

One standout feature is the interlocking mounting design. Male and female slots on each socket edge let you snap relays together in neat arrays, making it easier to route cables and maintain a tidy installation.

• Interlocking relays for organized layouts
• Color-labeled wires for straightforward wiring
• Integrated fuse socket saves space and cost
• Ready-to-install set: relays, harnesses, and fuses

Wiring essentials that simplify setup

The color-coded harnesses guide you through connections: Black for Ground (85), Red for VDC (30), White for Trigger (86), and Blue for Output Normally Open (87). This labeling supports quick identification and reduces guesswork during installs.

• Black ground (85) ensures solid reference
• Red VDC (30) powers the circuit
• White Trigger (86) activates the relay
• Blue Output NO (87) switches the load

Where it shines

Designed for broad automotive use, the Nilight 50023R kit supports tasks like power door lock or actuator control, trunk release, polarity changes, or converting a low-current signal to drive a higher-current load. It’s also suitable for adding ignition or accessory outputs and for simple motor or electronics control in 12V systems.

• Power door locks and actuators
• Trunk release and ignition/accessory outputs
• Polarity changes and load switching
• Converts low-current signals to higher-current loads

What you get in the box

The set includes five relays, five interlocking harnesses, and five 30A fuses, so you can start wiring with minimal setup. The components are designed to endure automotive environments while remaining straightforward to install.

• Five relays with fused sockets
• Five harnesses for easy, color-guided wiring
• Five 30A blade fuses for immediate protection

Final notes

This kit is built for 12V automotive applications and emphasizes practicality and clean installs. While it offers strong potential for simplifying wiring and organizing layouts, actual results depend on your vehicle and project specifics.
