This is a pack of four 12V 40A automotive relays. They're the standard 5-pin configuration, which is super common for all kinds of car accessories and electrical projects. They come in a waterproof housing, which is great for engine bays or any place they might get wet. The contacts are made of alloy for good conductivity and longevity. Whether you're installing fog lights, a horn, an electric fan, or troubleshooting some electrical gremlins, having a few spare relays on hand is always a good idea. These are unbranded but should do the job. Brand new, ready to wire in. Solid, basic relays for any 12V system.
