🚗 Nilight 50043R: Heavy-Duty Bosch Style 12V 30/40 Amp 5-Pin Relay Switch 10 Pack for Automotive, Truck, Marine & Boat - 2 Years Warranty Review

They appear to be waterproof. I installed them very easily in a semi-sealed spot on the outside of my pickup and held them up. Good value for money. recommended

Worth the money and more. No, not waterproof. Electricity and water are not good playmates. So do not use them in an aquarium or in the water on a boat 🤦

Ordered two sets of ten, received no metal mounting tabs, sent to the email address provided and received a quick response, two more sets of ten relays sent, again without the listed tabs to attach pictures abs , which I need for most of my applications.

We marked some seasons better than others. Cosmetics yes, just needed a little more care.

I am an electrical engineer and have had more than a few relays in my 40+ years in the business. I usually analyze the dead ones I replace to see what caused the failure, time permitting. Because of this, I have a pretty good idea of what to look for in a quality (or not-so-good) relay. I took one of these apart (needed a base to assemble the test equipment) and found that they were well made relays. Here's what I found (photos attached) - real copper coil windings on a plastic insulated spool,
