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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great *by T***. on February 4, 2026* Great for lights ### ⭐⭐⭐⭐⭐ Easy to install *by A***S on September 11, 2025* Good amount of light works well with Jeep ### ⭐⭐⭐⭐⭐ Nice wire kit *by A***R on June 12, 2024* Used this wire kit for my light bar on my SXS and it worked perfect.
