BMW M4 Laser Tail Lights: A Step-by-Step Installation Guide

Upgrading your BMW M4 with laser tail lights is a smart way to enhance its appearance and improve safety. The new BMW M4 laser tail lights not only look sleek but also provide better visibility on the road, making them a great choice for car enthusiasts. In this step-by-step guide, we will walk you through the entire installation process so you can confidently install BMW M4 with laser tail lights yourself.

Before we start, here’s what you will need:

Tools and Materials

• BMW M4 laser tail lights (make sure they’re compatible with your model)
• Screwdrivers (flathead and Phillips)
• Ratchet wrench set
• Trim removal tool
• Electrical tape
• Wire connectors (if needed)
• Gloves (for safety)
• Clean cloth

Step 1: Prepare for the Installation

Before beginning, ensure you have all the tools and materials listed above. It’s also important to park your BMW M4 in a well-lit and flat area to make the job easier. Turn off your car and remove the key from the ignition. Disconnect the car battery to avoid any electrical issues while working with the tail lights.

Pro tip: Wear gloves to protect your hands and prevent any smudges or scratches on the new lights or your car’s paint.

Step 2: Remove the Old Tail Lights

To start, open the trunk of your BMW M4. You’ll notice a plastic covering behind the tail lights. Pull off the plastic cover with gentle pressure using the trim removal tool. This will expose the screws or bolts holding the old tail lights in place.

1. Use a ratchet wrench to remove the bolts securing the tail lights.

2. Once the bolts are off, carefully pull the tail light assembly out of the car.

3. Disconnect the wiring harness connected to the back of the tail light. Set the old tail lights aside.

Important note: Keep track of all the screws and bolts you remove. You’ll need them for the installation of the new laser tail lights.

Step 3: Check the Wiring

With the old tail lights removed, inspect the wiring for any damage. Look for frayed or exposed wires. If you see any issues, now is the time to repair them with electrical tape or replace the wiring if necessary.

The new BMW M4 with laser tail lights may come with a plug-and-play harness, which makes the wiring simple. If the harness matches your car’s connector, simply plug it in. If not, you may need to use wire connectors to join the wires properly. Be sure to connect the corresponding wires—positive to positive, negative to negative.

Pro tip: Take a picture of the original wiring before disconnecting it. This will help you ensure the new lights are connected correctly.

Step 4: Install the New BMW M4 Laser Tail Lights

Now it’s time to install the new BMW M4 laser tail lights. Follow these steps to get them mounted:

1. Align the new tail light with the opening in your car’s rear. Make sure it fits snugly and lines up with the bolt holes.

2. Connect the wiring harness to the back of the new laser tail light. Double-check that all connections are secure.

3. Carefully slide the new tail light into position.

4. Using the bolts you removed earlier, secure the tail light assembly in place with a ratchet wrench. Don’t over-tighten, but make sure the light is firmly attached.

Step 5: Test the Tail Lights

Before you reassemble everything, it’s crucial to test the new BMW M4 laser tail lights to ensure they’re working correctly. Reconnect the car battery and turn on your vehicle’s lights.

1. Test the brake lights by pressing the brake pedal.

2. Check the turn signals and reverse lights.

3. Make sure all lights are functioning as expected.

If something isn’t working properly, double-check the wiring connections to ensure they are secure and correctly matched.

Step 6: Reassemble and Clean

Once you’ve confirmed that the BMW M4 laser tail lights are working perfectly, it’s time to finish up.

1. Replace the plastic cover that you removed earlier.

2. Reattach any screws or clips that were taken off during the process.

3. Give the new laser tail lights a final wipe-down with a clean cloth to remove fingerprints or dust.

Your BMW M4 now has brand-new laser tail lights that are not only stylish but also offer enhanced safety.

Benefits of BMW M4 Laser Tail Lights

Now that you’ve installed your new laser tail lights, let’s take a moment to appreciate their benefits.

1. Better Visibility: Laser tail lights are much brighter than traditional lights. They make your car more visible to other drivers, especially in poor weather conditions.

2. Modern Look: The sleek design of BMW M4 with laser tail lights adds a futuristic, high-tech look to your car.

3. Energy Efficiency: These lights consume less energy than older bulb technologies, which can extend the life of your car’s electrical system.

4. Longer Lifespan: Laser tail lights last longer than standard bulbs, reducing the need for frequent replacements.

5. Enhanced Safety: By being brighter and more noticeable, laser tail lights help reduce the chances of rear-end collisions.

Common Mistakes to Avoid During Installation

To help ensure your installation process goes smoothly, avoid these common mistakes:

Forgetting to disconnect the battery: Always disconnect the car battery before handling electrical components. This prevents electrical shorts and potential injuries.

Over-tightening bolts: While it’s important that the tail lights are secure, avoid over-tightening the bolts. This could crack the plastic housing or damage the lights.

Improper wiring: Be cautious when connecting wires. Mismatched connections can result in malfunctioning lights or electrical issues in your car.
