Adding Rear Work Lights to John Deere X500 Tractor

Unpackage all of the equipment and get it ready. The two LED lights have wiring connected to them already and additional wire will need to be connected to them as part of this project.

After purchasing the supplies listed above or using something else, the rear of the tractor will need to be prepared. Just behind the seat of my X500 there are two holes already in the body of the tractor, designed to be used for an enclosed cab accessory. Because I don’t have plans on using the enclosure and I’d prefer not to make new holes in my tractor, I decided to use these for my lights.

Prepare the lights to be mounted on the tractor by installing the brackets that are included. I was able to use the brackets, bolts, and nuts that came with the lights and did not need to purchase any other hardware.

The holes on the rear of the tractor behind the seat have two holes on either side. I chose to use one hole for the light mount and the other for the wire. Below is a picture from the underside showing the wiring and bolt coming through the hole.

Pro tip #1 – If using a wrench or socket, it is 10mm.
Pro tip #2 – In case you’re wondering what order to put the regular washer and lock washer on the bolt, it is lock washer first, followed by the regular washer as shown below.

Another benefit of mounting the lights this way is that they can swivel back and forth and up and down, allowing them to be easily adjusted based on the work you are doing. Below is a picture showing the topside of the tractor with the light mounted.

The lights have a very small profile, below is a picture showing what the lights look like from the side of the tractor.

The next step is to mount the second light in the same manner as the first. 

Mounting the lights is the easiest part of this project. Now that the lights are installed, the next part is wiring them to a power source. I decided to run my wiring from the battery and along the underside of the right side of the tractor. To do this, I roughly measured the distance between the front of the tractor (near the underside of the dashboard) and the rear of the tractor and cut a length of wiring. Next, I placed that wiring within the 1/2″ flex conduit to protect the wires. Once the wiring was inside the conduit, I found a channel that I could run it along the underside of the right side of the tractor that wouldn’t be impinged by any movement, pedals, etc.

On the front of the tractor, I had the conduit come out along the right side, just under the battery and fed it to the top of the battery. As a reminder, the red wire will connect to the switch we will eventually install and the black will connect directly to the ground wire of the battery. I did not connect the wiring to any power source yet, so I didn’t have to worry about working with any hot wires as I made my connections on the rear of the tractor. With the power supply wires at the rear of the tractor now, it’s time to connect the two rear LED lights together and to the power source.

The first step is to measure the distance between the two lights. Take this measurement from under the tractor and from the wire of one light to the other. Once you have this measurement, cut a length of braided cable sheathing and have this ready. Now, get two yellow butt connectors and your crimping tool. Next, get one heat shrink tube that is large enough to go over two butt connectors. With everything ready, slide the braided cable sheathing over the left light wire and push it up the wiring so it’s out of your way. Now slide the shrink tubing over the wiring and crimp on the yellow butt connectors to the red and black wires respectively. A picture is below showing what this should look like at this point.

Now that the left side is ready, the right side of the butt connector will have both the right LED wires going into it as well as the power supply wires from the battery. Once you have the two red and two black wires inserted into the right side of the butt connectors, crimp those as shown below.

With the wires all connected and shrink tubing heated and completed, the braided wire sheath that had been slid over the left wire and held this entire time can be released and pushed over the entire wiring as shown below.

With this done, zip ties can be added and the wiring pulled tight toward the front of the tractor. This ensures everything is well out of the way of the tires or anything else (note – you will see an additional cable that isn’t part of this project, for just these lights look at the wires within the cable sheath).

At this point, the rear of the tractor is done and the focus will move to the dash and battery. I decided to install a switch on my dash for the rear lights and found a spot that was easily accessible under the dash that had room for a switch. The switch I chose is one that has a waterproof covering on it. In addition to the switch, two crimp on connectors will be needed for the wires (hot wire from the battery and red wire to the rear lights).

I first drilled a small pilot hole in my dash, then using a 1/2″ drill bit, I drilled the hole for my new switch. After drilling the hole, I installed the switch.

For the next step, cut the red and black wires from the rear lights to length – the black wire will be shorter because it only needs to go near the battery, and the red wire will need to extend to the bottom of the new switch just installed. Use a splice connector to clamp on to a ground wire from the battery if one exists, otherwise clamp on a ring tongue connector to connect to the negative post of the battery. A picture below shows the splice connector I used for ground (note the red arrow).

With the ground wire connected to the rear lights, the red wire from the rear lights needs to be connected to one end of the new switch. A new wire needs to be created (red) that goes from the positive side of the battery to the new switch in order to provide it power. I used a splice connector for the new red wire leading to the switch just like I used for the ground wire. The below picture shows the splice connector on a red wire leading from the battery and also the wire I created that is coming from the switch on the dash. After the picture was taken, I connected these two.

Once that red wire is connected from the switch to the battery, try the switch and make sure both lights turn on.

After confirming everything works, clean up the wiring under the hood and dash by using zip ties. Below is a picture of what the red wires looked like when I was done with the project.

These lights have been great and made a huge difference.
