    Got me hooked UP!
    Color: 14AWG-2 Lead, Color: 14AWG-2 Lead
    This harness was easy to use long enough to reach all my lights and got me lit up in about an hour only because I had to drill holes for my lights themselves. The harness was super easy to use super easy to tie strap up, so it wouldn’t be seeing or keep out of the way of moving parts

    Good value, nice kit, simple install if you are OK with auto wiring.
    Color: 26Inch light White +Wiring Harness
    This is my second purchase of this light system. It is a great value for the money. It is pretty darned bright. The wiring harness is complete and would make for an easy install as directed. I'm an EE, so I did some hacks on the system myself, I added some connections to the existing headlight circuit so I could slave the high beam switch to the light bar. Now the switch included with the system functions as an arming switch for the light bar, rather than a simple on/off function. Prior, to turn the bar on and off, you of course used the switch. Now, the bar is slaved to the high beams, so both bar and stock high beams come on using the stock light lever on the steering column, and bar and high beams turn off when you set the lever to low beams. This allows the bar to act as a complement to the high beams, and for you to control them with the high beam lever after arming the system to do so. Overall, a great setup and good product. This bar is installed on my 2000 Fourrunner, my first is installed on a 2003 E350 where I did the first high beam+light bar trick.

    Brighter than my headlights on bright!
    Color: 26Inch Light White
    This Nilight 26 inch 540 watt 50,000 lumen Triple Row Driving light is the brightest light I've ever had on my truck. I bought a kit to mount the light to my Grill Guard, just above the bumper. I can see deer just like daytime, at least two blocks before I get to them. I've never seen a light bar as bright. There are no cons if you ignore the fact that it comes without a wiring harness. I definitely recommend this light bar!
