Plus, if you’re feeling creative and handy with tools, you can easily customize your own light bar to fit into the exact look and feel you’re going for.

Most LED lights come with all the necessary hardware, so there’s no need to worry about buying any extra parts – though having a few spare screws around doesn’t hurt! Plus, the installation process only takes a few minutes and can be completed with basic tools found in any garage.

How to Install Light Bar on Roof in 10 Steps

Step 1: Place the Light Bar

Place the light bar onto the roof of your vehicle to determine where you want it mounted. Make sure it is securely locked in place before drilling or cutting any holes. Also, make sure to check the area for any obstructions that could interfere with the mounting process.

Step 2: Mark the Drill Locations

Once you’ve determined where you want to place your light bar, mark the drill locations on the roof of your vehicle using a piece of masking tape. This will help ensure accuracy and prevent mistakes during drilling.

Step 3: Drill the Holes

Using a power drill, carefully drill the holes you marked in Step 2. Make sure to wear safety glasses and use a drill bit that is suitable for your vehicle’s roof material (metal or plastic). Drilling through metal will require a higher-powered drill.

Step 4: Install the Mounting Hardware

Using your socket wrench set, install the mounting hardware onto the roof of your vehicle. Make sure that all bolts are securely tightened before continuing on to the next step.

Step 5: Attach Light Bar

Insert the light bar into the mounting hardware and secure it with the provided bolts and nuts. Make sure the light bar is firmly attached to the roof before moving on.

Step 6: Run the Wiring

Run the wiring for your light bar along the inside of your vehicle, taking care to avoid pinch points or any other potential damage. Make sure that all connections are tightly secured and properly insulated.

Step 7: Connect Wiring to Power Source

Connect the wiring for your light bar to a 12v power source, such as a car battery or a fuse box. Depending on your vehicle model, you may need to install an additional relay switch if the current draw exceeds the capacity of the existing power source.

Step 8: Test

Once the wiring is connected, test to make sure that your light bar functions properly. If the lights are functioning correctly, then you can move on to the next step.

Step 9: Securing Light Bar

To ensure that your light bar is properly secured, you may want to use a silicone sealant or mounting tape around the edges. This will help prevent water or debris from getting into the connections and potentially damaging them over time.

Step 10: Enjoy!

All that’s left to do now is enjoy your newly installed light bar – you’ve earned it! From here, you can experiment with different lighting patterns and effects for an even more personalized look.

8 Safety Precautions to Follow Before Installing a Light Bar on Roof

Installing a light bar onto the roof of your vehicle is often necessary for off-roading and other night activities. However, it’s important to take proper safety precautions before doing so in order to ensure that you don’t end up with an accident or injury. Here are eight essential tips for safely installing a light bar on your roof:

  1. Make sure the roof is properly supported. Before installing a light bar, check to ensure that the roof can bear the weight of the lights and their mounting brackets without buckling or bending. This will help prevent any damage to your vehicle’s frame.
  2. Don’t install the light bar too high. If the lights are installed too high, they won’t be able to provide adequate illumination. Be sure to measure the height of your vehicle before installing the light bar in order to make sure it is at an appropriate level for optimal visibility.
  3. Securely fasten the brackets and wiring. Make sure that all mounting hardware and wiring are securely attached and not loose. If the wiring is not properly connected, it could cause a short circuit and damage to your vehicle.
  4. Wear protective gear when working with electricity. When handling electrical components, be sure to wear safety glasses, work gloves, and any other necessary protective gear in order to protect yourself from electric shock or injury.
  5. Use waterproof sealant. When installing the light bar, it’s important to use a waterproof sealant to ensure that no water can enter through the mounting points and damage your vehicle or wiring.
  6. Keep all components away from moving parts. Make sure that none of the electrical components are close to any fans, belts, or other moving parts in your vehicle, as this could cause a serious accident.
  7. Check the voltage and amperage of your lights. Make sure that the voltage and amperage of the light bar are compatible with your vehicle’s electrical system before installing it. This will help prevent any potential damage due to improper wiring or incompatible components.
  8. Don’t attempt to install it if you’re not comfortable. If you don’t feel confident in your ability to safely and properly install the light bar, it’s best to avoid attempting it yourself and seek the assistance of a professional or experienced technician.
