Review on Nilight 20 Inch 420W LED Light Bar Amber Triple Row Flood Spot Combo 42000LM Driving Boat Led Off Road Lights With 12V On/Off 5 16AWG Wiring Harness Kit, 2 Years Warranty by Brian Sitton

It was easy to install, provided you know what you are doing. They included everything to do it the right way - relay too! The harness was already pre-spliced incase you wanted to add additional light bars later.The only three issues I have is the button the switch on and off is a bit flimsy. If they included a beefy square button with a "led light bar" written on it, it would be a very good deal.Also the instructions are good at showing the electrical diagram, however, they didn't really show how the brackets were to mount on to the light bar. After a little trial and error I finally figured it out.I would recommend you use blue loctite on the threads otherwise they will vibrate loose over time. They should have included nylon nuts to prevent that.Other than these three small things, it's a very good deal for the money. I installed it yesterday - I hope it lasts a long time!
