      Review & Installation Video

      Hey, guys. Today, I'm here with the KC HiLITES H4 headlight conversion kit, fitting all 2007 to 2018 JK Wranglers. So, some JK owners do prefer the H4 headlight over the H13 stock headlight, because of a little bit of extra efficiency as well as a little bit of extra light output. So, this is for the JK owner that still like the look of their stock headlights, however they do want a mild upgrade. So, this is going to switch the H13 wiring harness over to the H4 wiring harness. However, it will still keep some of those same stock aspects, like the chrome reflector as well as the single filament halogen bulb. So, even though this will keep some of those same stock aspects to it, this will increase your lighting for better visibility on the street and on the trail. So at the moment, this is a very affordable replacement at roughly $130 on the page right now. There are other higher-priced options on the page. However, those will be made by premium brands and they'll have different designs in their lenses, and they can range anywhere from $150 to $300. Also, keep in mind that a single stock headlight replacement will roughly be the same price as this full conversion kit, so this is definitely a great option if you busted up a headlight on the trail and you're just looking for an overall replacement. Not to mention, these have great reviews and JK owners really seem to like this, so personally, I think for a mild upgrade, that these are worth the price. Install's going to be a very easy one out of three wrenches on the difficulty meter. All you need is about a half hour of your time and a couple of hand tools. So, speaking of that, let's jump into the install now.The tools that I used for my install were a trim removal tool, a flathead screwdriver, a quarter-inch drive ratchet, a quarter-inch drive small extension, and a T15 Torx bit. So, the first step to our install is popping our hood and popping off our grille. So, in order to pop off our grille, we need to remove the six pop clips holding it on top. So, I'm going to be using a flathead screwdriver to remove those. You can use a trim removal tool, but I would recommend a flathead screwdriver, just be careful that you are not scratching your paint. Now we can pull our grille forward and pop it out of the retainers on the bottom, being careful of our turn signal wiring harnesses. So, once you have your grille up and out of the way, you can disconnect your turn signals. So, you may need to pull up on that clip in order to release the harness, and then we can fully remove the grille. So, our next step to remove the headlights is to remove these four Torx screws around the headlight trim that are holding it in. I'm going to be using a T15 Torx bit, a small extension and a quarter-inch drive ratchet to remove those. So after the headlight pops out of place, you can disconnect the wiring harness and put this aside. Now, you can do the same thing on the other side. So, like I mentioned before, the new H4 conversion will be a mild upgrade compared to what comes stock in your JK right now. So, what you're really changing about this is the H4 housing and the H4 bulb, which will improve the wattage on the bulb. Taking a look at it side by side, they really are the same setup, so you do have the same chrome reflector, you will have a single filament halogen bulb, and they really don't look that much different. However, this will improve your lighting just that much more while you're out in the street and increase your visibility. So, the H4 conversion will give out roughly 2200 raw lumens collectively at the low beam, and roughly 3200 raw lumens collectively at the high beam, which is an improvement compared to the stock light, which will give you roughly 1500 raw lumens collectively at the low team, and roughly double that at the high beam, so you are increasing your visibility with this new setup. However, it will be a mild upgrade compared to other aftermarket options. This will also be a lot more durable even though it is a very similar setup. These will be able to take some abuse on the trail. So, these will have a hard-coated UV-treated Luminex lens on these. So, like I said, it'll be able to take a hit while still offering complete transparency, since it is basically a polycarbonate material. These will also be DOT approved just like your stock lights, so you are in the clear there as well if that's something that you were worried about. So, enough about our stock lights. Let's bolt up our new ones. So now we can install our light by pushing down on the rubber adaptor so it fits over there. This is going to make sure that everything is sealed, that water or mud does not get into the connection. Then, we can take our H4 to H13 conversion wiring harness, plug that into the back of our headlight, and then we can plug our H13 connection into our stock harness and pull down on our red clip. Now we can take our retaining trim, put that around our new KC light, and reinstall this with the four Torx screws that we originally took out to take out our stock light. So, you may have to switch this around and orient it in the right way in order to get your light in. Now, we can do the same thing on the other side. Now we can reinstall our grille, plugging our turn signals back in. So, once they're plugged back in, just press down that clip, the retaining clip, and you do it to the other side as well. So now you will have to maneuver around your winch if you do have a winch here. But, just be careful of your ambient air temperature sensor wire that is right on the inside of the radiator support. With that back on, you can give it a little love tap, and we can reinstall our six pop clips up top. Now we can shut our hood. So, that's going to wrap up my review and install on the KC HiLITEs H4 headlight conversion kit, fitting all 2007 to 2018 JK Wranglers. For more videos like this, keep it right here at

        Good upgrade over stock lights.

        These lights are a good upgrade over the stock lights. I didn't want to pay for LED lights at this time so I chose these lights. I'm glad I did.

        Headlamp upgrade

        Looks great, easy install. Better illumination than stock ever was and way better than the hazed over stock headlamps at a reasonable price.

        Great replacement light.

        Lots of people want to deck out their jeeps with fancy looking lights. This one is perfect for replacing the stock version. After many times of buffing out my factory stock lens, it seemed that I just couldn't get back a decent lens shine and night luminance was drastically affected by the dull lens. Well these KC lights definitely provide a brighter view at night and makes my jeep look new again. Great suggestion from my Extreme Terrain rep! Also, these were very easy to install and ET provided great how too videos!

        A lot better than stock.

        They are brighter than stock. They seem to project father and wider. A great in between for those not ready for the step up to led. Just don't expect high end led output.

        Clean classic look, easy install

        As advertised, these were easy to install and look great. Headlights are definitely brighter since the stock lenses had clouded up and degraded. Hardest part of install was getting the stock headlight off the harness but still only added 5 minutes to the 30 minute install time.

      I have a 2016 SAHARA from Canada with DRLs. Can you tell me if all bulbs and headlights that you sell are compatible with this function (DRL) thank you

      • All of our Halogen bulbs will function as intended with the DRL's in your Wrangler, however the LED bulbs will not work as they require full voltage to operate, and will flicker at the DRL's supplied voltage. Some complete LED headlamps, such as the KC HiLiTES Gravity LED 7 in. Headlights will be built to work with DRL's, and those that do will list this specifically.

      Ordered these for my 07 JK. One has gone bad, can I purchase a single lamp or do I have to buy the pair?

      • We are unable to offer pieces of this kit, we can only offer this as a pair. KC HiLiTES offers a 23 year warranty however, so it may be worth contacting our customer service department if you are experiencing a defect of some sort.
