Just what I needed !
I used these EHDIS 4-pin relays to replace a failing one in my car’s lighting system, and they worked perfectly. Installation was quick — the pins matched up exactly, and the build quality feels solid for the price. They've handled 12V and 40A loads without any issues, even after extended use. Great little relays to keep on hand for auto projects or quick replacements

Time it took to receive the order.
Relay was used as a replacement for a starter on a 500cc UTV and upon replacement the UTV started right off, no problem of any kind. Also was very pleased on the shipment of this item, very fast.

Fastest shipping i have ever experience.
I didn't post this. Edited to meet guidelines. These are the greatest relays i have ever purchased. The price was fantastic and shipping was unbelievably fast. I will order more just to have them and to experience the excitement of the fast shipping and handling.

Works well, but I made the mistake of not looking and seeing that these are nominally open. Get a 5 pin relay if you want nominally closed. My bad. Regardless they work exactly as they should.

Made of good solid material, could have the bolt holes a little bigger but it's not a huge deal at all, just make sure you get the 5 pack it's a way better deal
