How to install lights in a truck bed- Complete Guide

If you have a pick-up truck, you know the struggle it takes when you are trying to see what's in bed when it is dark. In this blog, we are going to learn about how to install lights in the truck bed. Together, let's know how to install truck bed lights. 

Materials and tools that you will be needing

You will need LED lights, a switch for the LED lights, a fuse holder, a primary wire, a wire harness, cable manager clips, a heat shrink, and electrical connectors. You will need a heat gun, a soldering iron, some helper clips, a pair of wire cutters, and strippers for the tools.

You can choose whatever LED lights you desire. Whatever styles, colors, and brightness. It's totally up to you. Also, make sure that the switch you purchased will fit the holes in the vehicle. So that, will not need to drill anymore.

You also need a fuse holder to protect the wires from short-circuiting. Two primary wires will be needed. One for the positive and one wire for the negative. The wire harness is used to protect the wiring.

In that way, the chance of you getting grounded is minimal. You will also be needing cable wire manager clips to make sure that the wires in the truck bed will stay put. Once you have all of those checked in your checklist, let's begin with the installation!

Splicing and Testing of Lights

In this step if your lights come in two strands, then you will need to splice them up. If not, then there's no need to splice it. Others don't require any alteration anymore, but if the one you bought has two strands, you will need to splice it.

It would be best to cut the wire about 2 inches from the light before weaving it. After you join the wire, make sure to connect it to the other lights by twisting them together. Once confused, solder them together, and then you will put the heat shrinker over two twisted wires.

Prepare the heat gun and seal them together. The next thing that you will be doing is testing the lights up. Make sure that all the lights turn on. Be careful when you're doing this, as you might get grounded.

Remember that the lights should has a (+) sign for positive and (-) sign for negative. Make sure that you don't connect them backwards. They should always be opposite from each other. 

The Installation Process

Figure out how long the wire will be from the front of the vehicle to the back. You will have to ensure that you have enough length as you will not want it to be too tight or too loose. After you measure, you have to add the fuse holder to the circuit.

You're going to remove the fuse and set it aside until we are ready to test out the whole thing. Get your wire cutter and cut the circuit in the middle. On one side of the course, you will need to solder it to connect it to the battery, while on the other side, you will solder it to the primary wires.

After soldering the wires, put a heat shrink to secure both ends. Once everything is all soldered up, install the wire harness to keep the cables connected and firmed.

Now you will attach the positive side of the wire to your car battery. You have two options on how you want it to get to the back of your truck. You can either have it go through the body frame of your vehicle or along with your car.

Once the wire reaches the back of the vehicle, install the switch. Leave extra lengths of the wire so that you can make the alterations in the future if you want to. 

Final Results 

Now you can flip the switch on and see the lights in your truck bed turned on. It is now easy for you to see everything behind your truck. It truly makes a difference, especially if you go out at night or when you love camping. When it's dark, it's tough to see what's behind your truck. That is why installing these lights are helpful.
