Review on 🚛 YITAMOTOR Single Row LED Light Bar 2PCS 18W 6Inch Spot Led Light Pods Offroad Work Light Fog Lights Driving Light for Truck Boat Tractors SUV ATV 4WD Car Golf Cart 12V 24V, 2 Years Warranty by Benny Suazo

I bought it because of the great price and enough positive reviews to not worry, but haven't seen it in action for a long time. However, I could not find anywhere in the product information whether special wiring harnesses and relays are needed. On delivery the installation instructions showed two circuits, one with a relay and fuse, the other with just a fuse. I read reviews that the relay is both needed and not needed. So the question is when to use a relay and when not to? I've sent a message to Amazon to find out but no response yet. How about unplugging my existing bulbs with the factory wiring harness and fog light switch and reconnecting the existing fog light wiring to these Yatimotors? Will that be enough?
