Review on 🚢 Waterproof 5-Pack Automotive Relay with Harness - 40 Amp 12V DC, 5-Pin SPDT Bosch Style for Automotive Truck Marine Boat Fan by Mdl Thurston

add this as a note, that all my judgments will be shorter until this hand heals. If the relay fails, it can cause serious damage and severe battery drain. Things can "stay" or "partially" and cause some real problems. I literally used TWO of these last week. I have TWO Mercedes Sprinters and BOTH fog light relays have failed. BOTH caused my battery to drain because I didn't know they were "on enough to drain the battery" and BOTH caused me great distress. I used these relays. Literally a minute later, my light came back on. Problem solved. I hope this review helps, and if so, please click the little USEFUL button next to my review. I smile when others find my reviews helpful!
