DZG Motorcycle LED Light Wiring Harness Kit 12V 2 Leads 30A in-line Fuse 40A Relay ON Off Switch 18AWG for Fog Lights Light Bar Driving Lights Auxiliary Work Lights

Installed this on my 2019 KTM Duke 390 a few weeks ago. Easiest part of installing a light kit was this harness. I wanted something that would allow me to cut power to ensure my LED light kit was off and not draining the battery. It’s a thick heavy duty wire that’s properly coated and covered, ensuring it can handle the inhospitable elements of an adventure bike, i.e. extreme heat, heavily waterproof, thrashing around in the backwoods etc. It was easily enough to run through the bike and only complications that arose were the small amount of space under seat on my particular motorcycle. The harness takes up a bit of space and due to that it was a tight fit to make it all work, luckily everything planned out and all is good. Another thing I liked on this harness is that it had the ring connector, providing a seamless connection to the battery without having to add the ring connector to it (you’d be surprised how many kits come with only the 2 wires, making extra steps and costs). It has a second attachment that you can also connect something else onto it, I will be doing a set of angel eye “fog lights” onto the 2nd slot. All in all it’s a well made and well thought out design that allows a user to connect a light kit and a secondary source as well. It gives you peace of mind that your battery is not being drained and it’s thick and coated enough to take the heat, water and road without any shorts. I would highly suggest and am looking at other products made by this manufacturer, specifically in terms of lighting and wiring harnesses. 5 stars

Worked great for my aux lights on my 2025 grom, good quality, easy install!

Solid harness with plenty of length for a single pair of lights/accessories. (ground and power leads are a bit short) Quality relay, connectors, and terminals. Only con is the SPST switch which is as cheap as cheap gets. Not sturdy, stylish, or the least bit weatherproof; recommend swapping with a proper grade switch. Otherwise a good buy. Note: if you have a dual circuit (high/low beam lights) and use a DPST/DPDT switch you will need to incorporate an additional pair of leads and add them to the relay connection interface. Some knowledge of wiring in parallel is necessary to do this.

I purchased this so I could cleanly retrofit a separate set of fog lights to my motorcycle. This allowed them to easily be straight wired to this wiring harness, and then to the battery. High quality wire, plenty of room to run it on a motorcycle. My only con is that the on/off switch is a bit cheap feeling. It has worked well over the past 10 months, but if anything were to break from this purchase, it would be the switch. Still giving it 5/5.

First time installing lights of this kind in a vehicle and this install kit made it 100% easier, had a blown fuse first time due to operator error but after a trip to the store and a quick fix it’s installed. Switch was easy to install and after a quick ride everything is holding up. Great product for the money hands down. They even come with stickers in the box to prove it was tested prior to shipping out.

It worked fine on my Kawasaki crash bar lights. They are very long. I cut about 3’ off. The on off switch is a cheapie but it works fine

Using this for aux driving lights on a motorcycle. This is a really nice harness. I ended up upgrading the connectors on the leads that go to the lights with DT connectors (also from Amazon). I read the reviews prior to purchasing and there were several complaints about the handlebar switch not being water proof. It's probably just fine as is but the underside of the switch isn't sealed with epoxy resin like some more expensive units would be. However, it you're concerned about that, just fill the bottom part with hot glue. I'm not that worried about it my application. I would buy this again.

I don't expect it to fail entirely. However, the relay did have issues after a few miles on my motorcycle. First, it was stuck in the off position, so my auxiliary lights wouldn't work. Then it was sticking in the ON position, which is BAD. Had I been on the trail, and needed to shut my motorcycle off, I would have had to QUICKLY tare the side plastics off to pull the relay or the fuse before it killed my motorcycle battery and left me stranded. Second, the relay type is fairly uncommon and I couldn't find a replacement at any stores in town. I ended up taking the relay apart and cleaning it with carb cleaner and placing it somewhere where water wouldn't drip inside of it, which I think it what caused the issue. It works now. But if it fails I'll rewire to a more standard 4 prong relay. Second, The inline fuse is like the least waterproof thing I've ever seen. It's basically just wires that go straight to the fuse. I replaced that with a waterproof one. The switch is also super low quality, and I think the solders won't last long. I expect to upgrade this to something different in the future. Overall it's fine and a good start if you are experimenting with some lights. Just expect to have to upgrade the switch, fuse, and relay at some point.
