Nilight 5 Pack Waterproof Relay 40/30 AMP 🚗
Product description
This waterproof relay and harness set brings reliable switching to automotive electrical projects, with protection against moisture and dust for outdoor use. The product suits installations where weather resistance matters, and it supports standard 12 V DC systems. The waterproof relay and harness set provides a practical mix of durability and straightforward wiring for lights, fans, and accessories.
Key points
Short and direct, the relays arrive prewired for fast installation and clear pin identification. They include a heavy duty harness with distinct wire gauges for power and signal, making setup easier even for hobbyists. The relays are sealed with a strong cap and seal ring to keep out water and grime, so the parts keep working after exposure to rain or wet roads. Tenacity matters in the garage and on the trail, and these parts aim to last longer under real conditions. Note that coil voltage is 12 V and can reach 14 V according to the original spec, these values refer to the coil operation rather than the switched circuit, so keep that detail in mind.
Tech specs
- What’s included: Nilight 5 Pack Waterproof Relay and Harness
- Type: 5‑pin SPDT automotive relay
- Power: 12 V DC coil, max 14 V according to manufacturer
- Material: tinned copper wires and durable relay housing
- Size: pack of 5 relays
- Color: black harness with black white red yellow blue wires
What’s included
The set ships with five sealed relays, five prewired harness sockets and a user manual for basic wiring notes. The harness uses heavy duty 12 AWG for main conductors and thinner 16 AWG for coil connections, so the kit balances current capacity and flexibility. Waterproof construction and tinned copper wiring are highlighted in the product details, offering corrosion resistance and easier soldering or crimping when needed. There are no extra mounting accessories in the package, so ten minutes of prep with screws or clamps may be required to secure the relays in a vehicle or enclosure.
Why it’s worth it
For hobby mechanics or installers who want weatherproof switching without complex wiring, this relay pack removes much of the guesswork. 40/30 AMP ratings give clear guidance on load handling, and the prewired sockets speed up repetitive installs. Keep in mind that these relays are intended for 12 V systems and the coil voltage note above may affect some niche setups. 😊
