Nilight Power & Electrical Editorial Review
The Nilight relay kit includes five sets of 30A relays with built-in fuses and harnesses. It can be used in a variety of applications, including nitrous and bottle heaters, remote door openers, fuel kill switches, and accessory wiring in classic cars. The relay switches can carry loads up to 30A, and the control side usually doesn't require more than a 16 gauge wire or 10A. However, some customers experienced loose spade connectors that could let the fuse fall off or not slide in snugly. The instructions can also be confusing, and the fuse could use a better method of installation. Despite these minor flaws, most customers found the relays easy to install and very reliable. Some of them have been using Nilight relays for a long time and prefer them over other brands.
