5 Pack Waterproof Relay and Socket Harness 40/30 AMP | Heavy Duty 12 AWG Tinned Copper Wires Pure Copper Core 5-PIN SPDT 12V Automotive Car Trucks RV Marine Boat

Used one so far, works great.

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!

Good product.

These relays are a good price for the quality. Nice and sealed and havent had a issue. Highly recommend these

These seem to work great though I just installed the first two yesterday so I don't know about their longevity. The water proofing seal is adequate. The wire insulation is good and fairly flexible. The wire is tinned as the description says, when you cut it, you can see what looks like copper (presumably). They are good in every way except for my complaint below. My only complaint and the reason for 4 stars instead of 5 is that the wire is not 12awh as advertised. It is a little smaller but definitely bigger than 14awg. I was able to use the blue (16-14awg) crimp connectors because of this. I used 12awg to wire the power source and that wire was definitely bigger and did not fit in the blue butt connector...this doesn't impact me too much but it is something to be aware of if you are actually running 30-40A through them...don't do that...I'm pretty sure they would melt. I put a 25A fuse in the circuit and it's probably only drawing 10-15A so it fits my needs just fine.

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.

Works

Works flawlessly, great product at a bargain price. And waterproof.

Bon relais, plusieurs mois d’utilisation dans le sel (Quebec) et la boue et reste étanche sans aucun vert de gris a l’intérieur ni humidité, a noter que j’ai mis de la graisse electrique. Beaucoup mieux qu’un simple relais ordinaire

Los relays llegaron a tiempo bien empacados y sin problemas. Al abrirlos el tamaño es un poco mas grande que los relays regulares. Los materiales se ven bien y además se sienten robustos. Hasta ahora los dos que instale están funcionando muy bien. También dan la apariencia de que resisten bien los elementos.

Good

Well made, good waterproofing, the wires were thicker than I imagined and that's good for connections. They are also copper which helps conductivity.
