Just what I needed !
The media could not be loaded. 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.
