How to Hide Light Bar Wires

When installing a light bar on your vehicle, the last thing you want is for the wires to show. This can spoil the appearance of your car and make it look untidy. In this post, we will show you how to hide light bar wires, so they are not visible. Follow these simple steps, and your car will look great!

Summary: Hiding light bar wires is essential for maintaining a clean and organized appearance in your vehicle, as well as protecting the wires from damage. Proper wire management ensures that your light bar functions correctly, prevents distractions while driving, and enhances the overall aesthetic of your vehicle’s interior. There are several methods for hiding and securing light bar wires, such as using wire loom, zip ties, adhesive clips, or conduit.

To effectively hide light bar wires, first, plan the wiring route to minimize visible wires, taking advantage of existing vehicle structures like the dashboard, headliner, or trim panels. Use a wire loom, a flexible plastic tubing that encases and protects wires, to bundle and conceal the wires as they run along the designated route.

Secure the wire loom in place with zip ties or adhesive clips, ensuring that it is firmly attached and out of sight. If routing the wires through tight or hard-to-reach spaces, consider using conduit or wire molding to protect and conceal the wires further. After the wires are concealed and secured, reattach any removed trim panels or vehicle components, making sure that the wires do not interfere with the proper functioning of any vehicle systems.

What Is a Light Bar?

A light bar is a device that emits a bright light, typically used for illumination or signaling. Lightbars are found on emergency vehicles like police cars and fire trucks, but they can also be used on construction equipment, tow trucks, and off-road vehicles. Some lightbars are even used for decorative purposes, such as storefronts or Christmas lights.

Lightbars typically consist of a series of LEDs arranged linearly, but they can also be round or square. The LEDs may be housed in a clear or frosted lens, and the entire unit can be mounted on a vehicle’s roof, bumper, or grill. While lightbars are available in various colors, white is the most common color since it is most visible during the day.

Why It’s Important to Hide Light Bar Wires?

If you want to make your car look different from everyone else’s, one of the best things you can do is change the lighting. You can get new, fancy headlights, or put a bright LED light bar on the roof. There are lots of ways to make your car look awesome with different lighting.

However, with all that focus on lighting comes a challenge: how do you keep those wires hidden and secure? After all, if they aren’t properly tucked away and secured, they can easily come loose or get damaged during driving. This is why it is so important to tuck your light bar wires away securely.

You can create a compact and customizable installation using innovative masking materials like tape or shrink-wrap sleeves without sacrificing functionality or quality. So if you’re ready to take your ride to the next level with top-notch auto lighting, start by taking steps to hide those pesky light bar wires!

How to Hide Light Bar Wires Step by Step Guide

Step 1: Find a Hiding Place for The Wires

This is the hardest and most time-consuming part of the project. You will need to find a place to hide the wires so they are not visible. This might mean taking off trim pieces, making holes, or running the wires through small spaces.

Step 2: Use Black Electrical Tape to Hold the Wires in Place

To secure the wires in place without being too noticeable, use black electrical tape. Begin by taping down the positive wire to the center of the light bar. Then, wrap the tape around the wire a few times. Repeat this process with the negative wire, making sure to leave enough slack so it can still be connected to the battery.

Connect to the Battery

Step 3: Cut a Small Hole in The Black Tape

To make connecting the wires to the battery easier, cut a small hole in the black tape. This will allow you to slide the wires through without removing the entire piece of tape.

Step 4: Thread the Wires Through The Hole

In order to connect the battery to the wires, thread the positive wire through the hole in the black tape. Make sure that the wire is long enough to reach the positive terminal on the battery. Then, do the same with the negative wire.

Step 5: Use Cable Ties To Secure The Wires

First, you need to figure out how you want your wires to be arranged. Once you have them how you want them, it’s time to secure them so they don’t move around and get damaged. To do this, you can wrap them with cable ties or electrical tape. We find that cable ties work best because they’re more durable and easy to remove if you need to access the wires again.

Wrap Them With Cable Ties

Step 6: Connect the Wires to The Battery

It’s time to connect the wires to the battery. First, strip about a half-inch of insulation off of the end of each wire. Next, use your knife to create a small slit in the black tape so that you can access the positive wire. Next, connect the positive wire to the positive terminal on the battery. Do the same with the negative wire and the negative terminal. Once the wires are connected, you can close up the slit in the tape.

Step 7: Test The Light Bar

Now that the light bar is securely mounted, it’s time to test it out. First, make sure the wiring is properly connected, and turn on the power. The light bar should come on without any issues. If it doesn’t, check your connections and make sure everything is tight and secure. Once you’ve confirmed that the light bar is working, you can enjoy your new light bar knowing that it’s safely and securely mounted.

Some Other Ways to Hide Your Light Bar Wires

1. Use Heat Shrink Tubing to Cover the Wires

This is probably the most common way to cover and protect your wires. All you need is some heat shrink tubing, which you can find at any hardware store, and a heat gun (or a hairdryer in a pinch). Then, simply tubing over the wires and using the heat gun to shrink it down, tightly covering the wires.

Use the Heat Gun

2. Use Wire Loom

Wire loom is a fabric sleeve that can be found at any auto parts store. It is designed to protect wires and hoses from abrasion and does a great job of hiding wires. Slip the wire loom over your light bar wires and secure it with zip ties.

3. Use Electrical Tape

Just use electrical tape for a quick and easy way to cover your light bar wires. Wrap the tape around the wires, covering all of the bare wire. This will protect the wires from exposure and also help to hide them.

4. Use Split Loom Tubing

Split loom tubing is similar to wire loom, but it’s easier to use because it splits down the middle, making it easier to slip over wires. Slip the tubing over your light bar wires and secure it with zip ties.

5. Use Cable Ties

Just use cable ties if you want a simple way to hide your light bar wires. Wrap the ties around the wires and secure them in place. This will hold the wires together and make them less visible.

6. Use Wire Clips

Wire clips are small plastic or metal clips that you can use to secure wires to a surface. You can find them at any hardware store. Attach the clips to the surface and then secure the wires to the clips. This will keep the wires in place and out of sight. Cut the Wire to Length

Use Secure Wires

7. Use Cable out of Sight

If you’re worried about hiding your light bar wires, you can always run the cables out of sight. This means running them behind panels, under seats, or through other areas where they’ll be hidden from view. This takes a bit more work, but it’s the best way to ensure that your wires are hidden.

Now that you know how to hide light bar wires, you can mount your light bar and rest assured that the wires are well-protected and out of sight.

Other Ideas to Consider

If you have your heart set on concealing your light bar wires, you can do a few other things. One is to use black electrical tape to blend the wiring in with your car’s paint job. Another option is to run the wires through the existing tubing or wire loom on your vehicle. Finally, you can purchase special tubing designed specifically for hiding wires. This option is more expensive, but it will give you a professional-looking result.

No matter which method you choose, be sure to tuck the wires away so they’re not hanging down where they can get caught on something or become damaged. And always use caution when working with electricity! Keep reading for more information about how to hide light bar wires.
