Fret not, as we have come up to answer how do you install LED headlights on a Jeep Wrangler? Hopefully, you can get a comprehensive idea of how to install them on your Jeep effortlessly.

The Jeep Wrangler

Before we get into the instructions, we should learn about what kind of vehicle we are dealing with. The more we know about it, the better we can understand how to apply the instructions for installing the headlights.

Jeep is a car manufacturing company that has been working on quality truck vehicles for a long time now. They made some of the best all-terrain trucks that you can use to traverse through any terrain without any hiccups.

Since it is an all-terrain vehicle, the Jeep has 4WD, meaning you can take control over all four of the wheels and move them however you want. This type of suspension design makes it easier for you to handle the vehicle easily.

Now, we come to the Jeep Wrangler. It is one of Jeep's most successful trucks because of its durable design and utmost reliability. In terms of lighting, its headlights are highly luminous and can light up the entire road effortlessly.

All of these reasons are why many people prefer the Wrangler over any other all-terrain vehicle as they find it most suitable for a wide variety of purposes.

Tools

To install LED headlights on a truck, you obviously require some tools to assist you in the process. These tools ease the process of removing the headlight boxes and fitting them with better headlights.

The main tools you will need are –

A screwdriver, both flat and star shapes, is preferred since different boxes have different-shaped screws.

A container to keep all the screws in one place.

The LED headlights that are going to be installed.

Instructions

After acquiring the necessary tools and knowledge of the vehicle, we can now proceed to install the LED headlights. Remember that it is a process that you should handle carefully; otherwise, you might end up with damaged electronics.

Screws

Your first task is to detach the screws and clips that are keeping the front grille suspended. Doing this will let you access the headlight boxes that are housing the headlights.

Bracket

Now, you have to remove the metal bracket ring that is keeping the headlight in place. Do this by unscrewing the four screws around the ring.

Adapter

Headlights usually power themselves using an adapter that is included in the vehicle. You have to remove this adapter to detach the stock headlights from the front.

LED Headlights

After removing all of the parts mentioned above, you have to install the LED headlights. The process is relatively simple as you put back everything how you removed everything in the first place.

Attach the metal bracket ring to the headlight, then plug the adapter into your vehicle. After fitting the headlight, put it back into the box and screw it in place.

Troubleshooting

If you see your headlights aren't working after installation, you may have run into some problems. Don't worry as you can solve these problems with the comprehensive guide we put together.

Installation

This could be a problem on the connection part. Recheck if you have connected the adapter and LED driver module box together correctly to solve this problem. If the pins are pushed out, make sure they are in place and out of the socket.

These problems may persist even after you have followed the guide, in which case you have to re-pin the adapter. Re-pinning can reset the adapter schematic, helping the headlight to connect appropriately.

Power

Headlights need the power stored inside the car's battery to operate properly. If the headlights don't get adequate amounts of electricity, they won't' turn on at all.

Make sure the headlight is connected to a capable battery. If the problem still remains, you may have to replace the battery since it might be empty or damaged.

Flickering

Generally, most lights operate by flicking the bulb incredibly fast, resulting in a broad spread of light. If the speed of flickering is slow, a strobe effect is created. It is a significant problem because you need the light from the headlights to be constant.

So, to fix this problem, you will require an anti-flicker decoder that makes sure the speed of flickering stays constant.

Localization 

In terms of electronics, the headlights could focus all of their light on only one side, leading to the other side being dark. If this problem occurs, you will have to access the LED driver module box, change the driver side to the passenger side, and see if the problem still exists.

By doing this, you will know what the cause of the problem is.

Finalization

Once you've checked all the issues, turn on the headlights and see if they work correctly. If they lit up without any hiccups, then you have successfully installed the headlights.

Final Words

Typically, most people do not know how to deal with the mechanical aspects of their respective vehicles. This is truer if we are talking about installing headlights on a vehicle like the Jeep Wrangler.

However, you can see the various advantages of having LED headlights on your Jeep. If you were also pondering on how do you install LED headlights on a Jeep Wrangler, we can guarantee that this guide should help you answer that question.
