KC HiLiTES (6307) H13 to H4 Headlight Conversion Cable - Pair

These plugged right into the stock wire harness with the h13 plug and were able to click in. They come with electric grease and worked amazing to update the lights to H4 100/55 bulbs. I did purchase the Hella glass 178mm, 7 in, lenses. They are much better than before and the total cost was about $100 for both headlights. Took about 30 minutes to change and was prob the easiest and cheapest thing you can do on your jeep.

So far KC has been amazing to deal with as far as customer service goes. 23 year warranty is pretty hard to beat. I've had gaskets and light housing parts rust out or break and they will send a replacement without question.Theis part replaces the wire harness adapters for a Jeep Wrangler. I've had them about 3 years and one light has been flickering. Bought new bulbs. Kept happening. This should do it. Will update if it didn't fix the issue.

One of these harnesses was not wired right from the factory. I used these to connect some new Rampage lights with H4 bulbs in my 2012 Jeep Wrangler. Once installed I checked the hi beam function only to find that one of them was not working. I figured it was a defective bulb. I went out and bought some Phillips Crystal Vision Ultras to replace the no name bulbs that came with the Rampage lights. After installing the new bulbs... Same thing... No hi beam on one side. I then checked all the connections on that light... Everything checked out. Then I compared the two harnesses. One was clearly wired differently. I took the connector apart and wired it the same as the one that was working correctly. Problem solved. Not a big deal for me as I was planning on getting better bulbs anyway... But it might be a pain in the a## for someone else. So... these work like they are supposed to and I recommend them... Just check and make sure both harnesses are wired the same.

One worked for a week and then the other one went out a month later… bought KC because I thought they’d be worth something but obviously I was wrong

I went through two sets of these from Delta for the halogen lights I got from them for my 2010 Wrangler. They required zip ties and locking pliers to get a good connection, but always failed after some time. The KC adapters fit so much better, and they required little effort to install. I wish I had found these two years ago!

I had trouble with LED lights not working that I was installing to replace stock headlights on a 2014 Wrangler JKU. I almost sent them back but this KC Hilite product did the job. Boom - lights! The pigtail cables that were supplied were wired wrong and these pigtails are corrective for that issue. The plugs are nice and tight-fitting also.

Eighteen months ago, I had installed the IPF brand H4 headlight conversion kit. Last week, my headlights started to not work. I took them out to check the bulbs and I found that when I bent the IPF wiring harnesses a certain way, the lights started to work again. So, I ordered these KC harnesses to replace the bad IPF harnesses. These plugged right into the stock Jeep wire harness with no problems at all. The headlights now work perfect again. I would definitely recommend these if to anyone doing an H13 to H4 conversion.

These look fine, I had assumed they would fit but I needed male connectors instead of female.

Worked well

Worked perfectly, worth the money if you're converting to an H4 lamp on your vehicle. Had some thoughtful extras included; dielectric grease for the contacts and zip-ties to keep the loose-fitting Chrysler connectors on. This kit was more expensive than other versions, but I went with KC HiLiTES because of previous experience with their products. All the components are well made and the wiring is sturdy and tight. I have no negative comments at all. Vendor shipped fast, item was brand new, perfect condition.

I connected these from my Jeep to the KC lites with no problem.

These are fantastic!! Nice touch that KC included some dielectric grease to put on the electrical contacts to prevent corrosion.They arrived at my place quickly and made the conversion from stock Jeep JK headlight bezel and H-13 bulbs(which are dismal at best)...to the Cibie headlight bezel and H-4 Philips x-treme 130 bulbs a breeze...what a difference doing this conversion has made!!!! Nice bright white light...hurray I can see at night again!!!!
