Review on 🔌 5 Pack Bosch Style Waterproof Relay Kit: 12V 5-Pin [Harness Socket] [12 AWG Hot Wires] [SPDT] [30/40 Amp] Automotive & Marine Relays for Boats, Auto Fans & Cars by Phil Show

I've used them for vehicles and for Halloween. They are waterproof, at least splash and splash proof. The cable pigtails are of high quality, the seals are silicone, the relays are strong, there is a diagram directly on the relay how to connect. I like to buy parts and tools that I can rely on and I have purchased these relays more than once.
