Review on High-Performance 1 Pack 40/30 AMP 12 V DC Waterproof Relay and Harness - Heavy Duty 12 AWG Tinned Copper Wires, 5-PIN SPDT Bosch Style Automotive Relay by Jerry Mills

The relay assembly looks very well built, it consists of 3 parts: 1. Waterproof housing: This keeps the relay in place and keeps it dry.2. Relay: securely mounted in a waterproof case and can be replaced if necessary.3. Waterproof connector: Cables connect here (on the outside), it has a silicone O-ring to protect against water and fits perfectly into the waterproof case (see 1), and it also has a connector that connects to a relay . Inner part. It appears to be a very well thought out design and it looks like it will survive being submerged under water for a long time. I bought it to hook up some lights to my motorcycle and it's exactly what I was looking for in terms of waterproofing/conservation. dry electronics.
