Nilight 50003R Automotive Set 5-Pin 30/40A 12V SPDT with Interlocking Relay Socket and Wiring Harness-5 Pack, 2 Years Warranty

Nice packet of 12v 5-Pin automotive relays with attached pigtail connectors. Appear well made, well marked, good materials used and have built in mounting tabs which are a plus. Nice 30/40 Amp rated, comparable with most common 5-Pin 12V relays found on automotive accessory devices. Easy to install using the pigtail wiring instead of having to make individual connectors. The 5 pack is a good value for anyone adding accessories like lighting to a vehicle.

They work great. Fast, easy, good price.

The price is certainly right! What I like about this product is that it includes the connection socket with colored wires. What I found difficult with this product is that the connection socket slots are not perfectly aligned to accept the blades of the relay assembly. (It appears the socket was assembled without care). If one attempts to insert the relay assembly with force, it will damage the socket since not all of the blades line up to the haphazardly assembled socket. One has to first carefully match the relay blades to each slot in the socket by slightly bending the ones that don't fit precisely. Then the relay will insert without damage or difficulty. My brother's Jeep has messed up wiring in the low beam headlight circuit somewhere in the wiring loom. We used one of these relays to just rewire the low beam circuit to go around the bad wiring. The relay is controlled by the regular low beam switch on the steering column so the car still functions as if its original wiring was still in play. (We disconnected the original wiring from the low beam light filaments and replaced it with the output of the newly installed relay)! So far, it has been working perfectly for the past 2 weeks! What is still a mystery is how long will this relay continue to function seeing as it is from China? As an aside, one should 'cap off', (or at least tape off), the end of the unused red wire. It is a funtional wire connection to the relay that is not normally used.

The instructions & photo are Wrong they say 85 is black ground. Then photo wire is white ? reversed 🤔 & 86 is ground. Which one is correct?? Looks to be a quality product. *Also choose because says delivered 6am-11am over night. They arrived 6:30pm in evening just saying

Use these for a cel overide on Mazdaspeed3s on VTCS delete, work Awesome. Thought they might be too much amps but just fine!

Excelente y buena calidad. Tienen un precio muy accesible y más económico que en otros lugares.

Used these for some LED light work on my truck and every single one worked perfectly with no surprises. The wiring diagram printed right on the relay is super helpful when you're doing your own install and don't want to keep looking stuff up. Having the harness included means no splicing which saves a ton of time and makes the whole thing look cleaner. Really solid kit especially for a 5 pack at this price.

Once a person considers the needs for a relay panel, it becomes evident that these items do not best suit the situation. It is far better to anchor the sockets, rather than the relays. Anchoring of relays requires removal of a screw, whereas anchoring the socket allows the relay to be easily replaced. Making this set worse, is the fact that the sockets do not slide together easily. They start alright, but they do not continue to slide all the way without unnecessary force. Further, the idea of interconnection offers no improvement to the wiring layout of the panel. I do not recommend this product, and I am sorry I bought it.

El arnés se ve de buena calidad, el cable que tiene es grueso, los relay entran justo en el arnes, hay que ver cuánto duran los relay

I bought these as for a truck project, and thank goodness I bought the 5 pack. The wires are very good thickness, easy to understand schematics, and you can pull out the wires that aren't needed (3-4-5 PIN) to complete your project. I have connectted accenting lighting to LED Bars to this relay.

Used to add a relay to serve as a signal for connect to the high beam working as switch for shutting off the fog lights, working well and quality are pretty devent.

Funcionó perfectamente para mi proyecto

they work great and are way cheaper than buying at local stores.
