Nilight 5 Pack Waterproof Relay and Harness 40/30 AMP Heavy Duty 12 AWG Tinned Copper Wires 5-PIN SPDT Style 12V Automotive Relay and Harness Set

Great 5 pack of relays and matching tails. I had old relays taped together running my Fisher plow lights. Weird light issues had me questioning these relays. These straightened out my concerns about cross wiring, and made the connections truly waterproof. Bam! Lights work correctly again.

This is awesome! I used it to turn my golf cart off and on since EZGO key's are a joke and they can be turned on with paper clip. Now I can use the fob to turn it off when I get off and won't worry about it getting stolen. Would buy again!

Excellent quality. Works exactly as described. Easy to install

I was looking for less expensive relays for replacing relays on my CAT Skid Steer. These same relays are used for both engine starter relay and the glow plug relay on the skid steer. I paid about $37 for one relay at the CAT dealer, while this whole five pack of relays are way less than that. I was thinking these Nilight relays would be lower quality, but now I have a different opinion. I weighed the Nilight relay vs the well used, original CAT relay (sorry for the dirt and dust), and they were exactly the same. I tested one relay with a 9V battery, and they had a very solid, distinctive click when the relay contacts changed state. My ohmmeter confirmed the contacts changed state properly. I confirmed the CAT relay fit into the connector the same as the Nilight relay. It is a very tight fit, but that is due to the rubber gasket that prevents moisture intrusion. The icing on the cake is that these Nilight relays are a straight plug and play, no rewiring required. That rating for 10,000,000 cycles may be a stretch, but who knows, it is looking pretty good so far!

Great product and works as described. Easy to install and the additional items and wire makes installation universal. The device is installed on the ground/negative side, between the ground cable and the battery. There is a small red wire that connects to the battery and supplies the relay power. The key fob has an on/off that works perfectly, and while off, the ground/negative signal is interrupted.

I use this to toggle on and off a positive battery terminal end that I brought into my truck to hook up a 800 watt (peak) power inverter. This means the inverter will pull a max of about 67 amps, well below the rating of the relay. It works great, wiring is the same as a regular relay.

Very good quality at a very good price just need to check because they are negative and positive relays

Excellent, works well, I recommend it.
