## Questions & Answers

**Q: Will this work with nilight 18026c-a 37inch 780w triple row flood spot combo bar 78000lm driving waterproof led work light off-road t?**
A: Are you sure the Watts you quoted is correct? 780w at 12V is 65Amps. I doubt this bar needs that. Its probably an equivalent to halogen light level. Check the actual current this draws. Then text  me back. I see other users use a 30Amp fuse. So im pretty sure this kit will be fine

**Q: Why does my light bar sometimes stay on and not shut off?**
A: You have it wired wrong, use ignition power, so when car/truck is off the light bar turns off 100% of the time.

**Q: The lights will not go out. Even disconnection swith will not turn lights off (have to pull fuse). T**
A: I would check the connections on the relay itself if it’s wired backwards it can keep the power on all the time

**Q: Trying to understand the wires that go to the rocker switch, is black for ground ( - ), red for battery (+), and white?**
A: Coming out of the relay are 3 sets of 2 lead wires, ..2 black (ground, attach these to the top left and right of the back side of the switch # 7,8), then 2 red, Positive,one will go to the single middle connector, #2. Now here’s your choice, if you want the face of the switch to light up even when the switch is “off”, hook up the other red lead to # 6 on the bottom right. If you don’t want the switch to always light up when “off”, then hook up the white 2 leads to #3 &6.  Wrap electrical tape around the extra wire, either red or white, that’s not connected according to your choice. Hope this helps.

*by G***N on May 30, 2021*

Purchased to go with my Nilight 37 in LED light Bar. Very pleased with the harness and switch. The harness comes with an in - line fuse and relay. Super easy to install with the only thing I needed was electrical type to provide additional weatherproofing to one required connection and a few zip ties. All connectors and spare fuses provided along with simple to follow instructions for those not familiar with 12 v wiring. The wiring length is enough for most any configuration / location of switch.
