Nilight 10016W DT Wiring Harness Kit for LED Light Bars - 12V On/Off Switch, Power Relay, Blade Fuse - 2 Leads

This was a great kit with the deutsch connector to go with some lights i got second hand that had the deutsch connector already on them from the factory so it was truly plug and play and I have to spair connectors to use ifni change my lights

I used the Nilight DT Connector Wire Kit to wire up the fog lights on my Ford Raptor, and it worked perfectly. The connectors are well-made and weatherproof, giving me peace of mind that they’ll hold up against moisture and dirt. The wiring kit made installation much easier and cleaner compared to splicing wires, and the plugs fit securely with no loose connections. Everything looks professional and functions flawlessly. If you’re installing fog lights or other auxiliary lighting, I’d definitely recommend this kit for a solid, hassle-free wiring solution.

The wiring harness appears to be great quality! The 14 AWG is very heavy duty and everything is double insulated. In my case, LED pod lights on a motorcycle it was overkill and excessively long. I think 16 AWG would be better. I cut out all the extra slack and spliced the wires to custom fit my application. The wires are not solid copper. It comes with a 25A fuse. So I recommend calculating the size you need. In another users review they mentioned to cut the yellow wire from the relay and splice it to a 12v power supply that turns on with the key. This prevents the led light from always being on and will only activate the relay when the key is turned on. Super helpful cause I didn’t want extra battery draw! I spliced it to the license plate light and achieved the same results. It’s great it came with connectors as well. This is exactly what I needed and is a great value. I would recommend to add another switch option that is more low profile and waterproof other wise the included one worked perfect.

I purchased this harness because it had everything that I needed to install the aux lights on my 2007 BMW R1200GS. (switch, fuse, relay and waterproof disconnect cables to the aux lights) The switch was the main disappointment with the harness. it didn't look very sturdy nor waterproof and came with a double sided tape to mount. So I purchased a waterproof handlebar switch on amazon and cut off the original switch and spliced in the new one. Excellent decision. This harness is designed for use on a off-road vehicle so the length of all the cables were way too long for my setup. no problem. After mounting the lights I "dry" fitted, routed the harness and marked where I had to cut and splice. I used waterproof crimp connectors, heat shrink tubing and a felxible hose to route the shortened harness to the bike. I was able to find a great spot to mount the relay and fuse under my seat to protect them from getting wet. I am still very happy with the purchase. it took a little longer to install the harness, but it is well designed and my cutting and splicing didn't harm it. I am very happy with the additional aux lights on my bike and would recommend this item for use on any motorcycle installation. I am not very comfortable with doing electrical stuff on my bike but the installation diagram is easy to follow and I have no issues after all the modifications I have done to the harness.

Worked great, easy to install

I ordered this harness for an add-on set of driving lights for my Wagoneer. This harness is exceptionally well made, and you can tell it will last. The connections seem very solid, and the wiring is covered with heat-shrink tubing. I added some wire wrap at the points where the harness will pass through metal as a precaution on my part. It appears to be long enough for nearly any vehicle. The relay is rated for 40 amps and appears to be well-constructed. The battery to the relay fuse is blade-style, 25 amps, and replaceable. The only questionable feature is that the switch has a red LED light that remains on when connected to battery power. I'm not sure if a switch with a light is necessary. I’m concerned that if the vehicle isn’t driven frequently, the light could drain the battery over time. I'll test the current draw on the switch before I install it.

If you have a set of LED lights that didn't come with a harness , you can't beat this for the price. By the time you figure in the cost of the parts ( wire, switch, crimps/connectors, not to mention a relay if you are using one) to hardwire a set of lights, let alone the time to assemble, this set up is cheaper by far. harness length is ample, you get a pair of pigtails with connectors for a pair of lights, the relay, switch, fuse block and fuse, and ring terminals for power all assembled for what a switch and some wire would cost. Made everything quick, cheap, and easy.

I love these harnesses, I wish at times that I can get them in 12awg instead of 14awg but they work. Easy to install and user friendly with any lights that you want to use. I don't recall having any issues with NILIGHT PRODUCTS. When it comes to the off road lighting ✨️ NILIGHT is it for me. Other types of lighting like trailers, I use about 3 companies and it really comes down in how bright, looks, how long they will last, durable, ease of use and product choices and a couple more options but I want results for the money and how well they work. Remember that when you're out there in the night getting to or trying to get back home or the campsite and it's so dark that you can't see your hand in front of your face and your lights just quit after a short time of usage, you'll be pissed. I've been in places that it's so dark that it'll eat that light if it isn't really bright. So you want to rely on the lighting and the harnesses and hardware to work to get you to your destination safely and so far this company is my go too for that. I will continue to buy again and again. Update 01/09/2026: I want to say that apparently NILIGHT PRODUCTS must be reading these reviews (not just mine but all reviews). I recently purchased and waiting on delivery a couple of harnesses that are 12awg instead of 14awg. Some of the lights that I have bought recently, I feel should have the heavy wire for both making sure that power is getting to the lights and that I don't have to worry about harness failure because they are getting hot due to power needs and to small a wire. I have used this description a couple of times in other reviews. Electricity is like water, you can't put out a fire by using a small hose and some applications don't require large wires and the 14awg or even the 16awg will do the job safely. Always side on safely, you don't want to have a fire using the wrong size. Sorry for going the long way to the barn door.
