How to Turn Off Daytime Running Lights Infiniti Q50

Turning off daytime running lights (DRLs) on your Infiniti Q50 isn’t always straightforward, but it’s possible with the right tools and knowledge. This guide walks you through factory settings, fuse removal, aftermarket modules, and professional options—ensuring you can customize your lighting safely and legally.

If you’ve ever driven your Infiniti Q50 during the day and noticed the headlights glowing at a low intensity—even when the car is in park—you’ve experienced the vehicle’s daytime running lights (DRLs) in action. These lights are designed to increase your car’s visibility to other drivers, reducing the risk of accidents during daylight hours. While DRLs are a safety feature mandated in many countries, some Infiniti Q50 owners find them unnecessary, too bright, or simply prefer the look of fully off headlights. Whether you’re parking in a garage, trying to reduce glare, or preparing for a car show, you might be wondering: *How do I turn off the daytime running lights on my Infiniti Q50?*

The good news is that it’s possible—but not always simple. Unlike some vehicles that allow you to toggle DRLs on and off through the infotainment system or dashboard settings, the Infiniti Q50 doesn’t offer a straightforward menu option. This means you’ll need to explore alternative methods, ranging from basic fuse removal to advanced reprogramming. In this comprehensive guide, we’ll walk you through every viable option, explain the pros and cons of each, and help you make an informed decision based on your needs, technical skill level, and local regulations.

Before diving into the how-to steps, it’s important to understand what DRLs are and why they exist. Daytime running lights are low-intensity headlights that automatically turn on when the engine is running and the vehicle is in drive or neutral. They’re not as bright as full headlights but are bright enough to make your car more visible in daylight conditions. In countries like Canada and much of Europe, DRLs are legally required. In the U.S., they’re not mandatory, but many manufacturers—including Infiniti—include them as standard equipment for safety.

Now, if you’re set on disabling them, you’re not alone. Many Q50 owners seek this modification for aesthetic reasons, to reduce electrical load, or to prevent premature bulb wear. However, it’s crucial to proceed carefully. Disabling DRLs can sometimes affect other systems, trigger dashboard warning lights, or even violate local traffic laws. That’s why this guide emphasizes safety, legality, and reversibility. We’ll cover everything from quick fixes to professional solutions, so you can choose the method that best fits your situation.

Understanding Daytime Running Lights on the Infiniti Q50

To effectively disable your Infiniti Q50’s daytime running lights, it helps to first understand how they work. The Q50 uses a combination of LED and halogen lighting systems, depending on the model year and trim level. Most newer Q50s (2014 and later) come equipped with LED DRLs, which are more energy-efficient and longer-lasting than traditional bulbs. These lights are controlled by the vehicle’s body control module (BCM), a computer that manages various electrical functions.

When you start the engine, the BCM sends a signal to activate the DRLs. They remain on as long as the engine is running and the parking brake is not engaged. Unlike traditional headlights, DRLs operate at a lower voltage or use a different circuit to reduce brightness. This is why they appear dimmer than your full headlights but are still clearly visible during the day.

One key thing to note is that the Infiniti Q50 does not have a user-accessible setting in the dashboard or infotainment system to turn off DRLs. You won’t find a “DRL Off” button or menu option like you might in some European or luxury vehicles. This means that any attempt to disable them will require either physical intervention (like removing a fuse) or electronic reprogramming.

It’s also worth mentioning that disabling DRLs may affect other lighting functions. For example, some systems tie DRL operation to the automatic headlight sensor. If you disable DRLs improperly, you might notice that your headlights don’t turn on automatically at dusk, or that the instrument panel displays a warning message. In rare cases, the car’s onboard diagnostics system may log an error code, which could complicate future service visits.

Understanding these nuances is essential before making any changes. The goal isn’t just to turn off the lights—it’s to do so safely, legally, and without unintended consequences. With that in mind, let’s explore the most effective methods for disabling DRLs on your Infiniti Q50.

Method 1: Removing the DRL Fuse (Quick DIY Fix)

For many Infiniti Q50 owners, the quickest and easiest way to disable daytime running lights is by removing the DRL fuse. This method requires no special tools or technical expertise—just a few minutes and access to your vehicle’s fuse box. It’s a popular choice for those who want a temporary or reversible solution.

Locating the DRL Fuse

The first step is to find the correct fuse. In most Infiniti Q50 models (2014–2020), the DRL fuse is located in the interior fuse box, typically found under the dashboard on the driver’s side. To access it, you may need to remove a plastic panel or cover. Refer to your owner’s manual for the exact location and fuse diagram.

Once you’ve opened the fuse box, look for a fuse labeled “DRL,” “Daytime Running Lights,” or something similar. It’s usually a 10-amp or 15-amp fuse. If you’re unsure, cross-reference the fuse box diagram (often printed on the inside of the cover) with your manual. Some models may use a relay instead of a fuse, so be prepared to identify the correct component.

Safely Removing the Fuse

Before removing any fuse, make sure the engine is off and the key is removed from the ignition. This prevents electrical surges or accidental short circuits. Use a fuse puller tool (often included in the fuse box) or a pair of needle-nose pliers to gently pull the fuse straight out. Avoid twisting or bending it.

Once the fuse is removed, start the engine and check if the DRLs are off. If they are, you’ve successfully disabled them. However, be aware that some systems may still illuminate other lights (like parking lights or side markers) even with the DRL fuse removed. This is normal and depends on your vehicle’s wiring configuration.

Pros and Cons of Fuse Removal

The biggest advantage of this method is simplicity. It’s free, requires no special tools, and can be reversed in seconds by reinserting the fuse. It’s ideal for temporary use—like during a car show or when parking in a dark garage.

However, there are downsides. Removing the DRL fuse may cause the vehicle’s computer to detect a fault, triggering a dashboard warning light (such as the “Check Engine” or “Lighting System” indicator). In some cases, this can affect other systems, like automatic headlights or rain-sensing wipers, if they share the same circuit.

Additionally, if you live in a region where DRLs are legally required, disabling them could result in a traffic citation. Always check your local laws before proceeding.

Method 2: Using an Aftermarket DRL Disable Module

If you want a cleaner, more reliable solution than fuse removal, consider installing an aftermarket DRL disable module. These devices are designed specifically for vehicles like the Infiniti Q50 and offer a plug-and-play way to turn off daytime running lights without permanent modifications.

How DRL Disable Modules Work

A DRL disable module is a small electronic device that intercepts the signal between the vehicle’s computer and the DRL circuit. When installed, it prevents the DRLs from activating while leaving all other lighting functions intact. Most modules are designed to be reversible—simply unplug them to restore factory settings.

These modules typically connect directly to the DRL wiring harness, often near the headlight assembly or under the dashboard. Installation usually takes 15–30 minutes and requires basic tools like a screwdriver and wire strippers. Some models come with detailed instructions and even video tutorials.

Choosing the Right Module

When shopping for a DRL disable module, look for one that’s compatible with your Infiniti Q50’s year and trim. Popular brands include Diode Dynamics, OPT7, and LASFIT. Read customer reviews and ensure the product is designed for LED or halogen systems, depending on your vehicle.

Avoid cheap, generic modules that may overheat or fail prematurely. A quality module should include surge protection, waterproof housing, and a warranty. Some even offer remote control or smartphone app integration for on-the-fly control.

Installation Tips

Before installing, disconnect the car’s battery to prevent electrical damage. Locate the DRL wiring—usually a yellow or white wire in the headlight harness. Follow the module’s instructions to splice or plug into the circuit. Use electrical tape or heat shrink tubing to secure connections.

Once installed, test the system by starting the engine. The DRLs should remain off, while your headlights, brake lights, and turn signals should function normally. If you notice any issues, double-check your connections or consult the manufacturer.

Advantages Over Fuse Removal

Unlike fuse removal, a DRL disable module doesn’t trigger warning lights or affect other systems. It’s also more convenient—no need to crawl under the dashboard every time you want to toggle the lights. Plus, it’s fully reversible, making it ideal for resale or lease vehicles.

The main drawback is cost—expect to pay $30–$80 for a quality module. However, for many owners, the peace of mind and reliability are worth the investment.

Method 3: Professional Reprogramming via Dealership or Technician

For the most seamless and permanent solution, consider having your Infiniti Q50’s DRLs disabled through professional reprogramming. This method involves using specialized diagnostic tools to access the vehicle’s computer system and modify the lighting settings.

How Reprogramming Works

Infiniti dealerships and certified technicians have access to tools like the CONSULT-III or newer versions of the manufacturer’s diagnostic software. These tools can communicate directly with the body control module (BCM) and change settings that aren’t available to the average user.

During the reprogramming process, the technician can disable the DRL function entirely or adjust its behavior (e.g., reducing brightness or delaying activation). The change is stored in the vehicle’s memory, so it persists even after the battery is disconnected.

Benefits of Professional Service

The biggest advantage is cleanliness. There are no wires to splice, fuses to remove, or modules to install. The car operates exactly as it did before—except the DRLs are off. This method also avoids any risk of triggering warning lights or affecting other systems.

Additionally, if you ever decide to re-enable the DRLs, the technician can reverse the change just as easily. This is especially useful if you plan to sell the car or return it at the end of a lease.

Cost and Availability

The main downside is cost. Dealerships typically charge $100–$200 for this service, depending on location and labor rates. Independent shops with Infiniti expertise may offer lower prices, but ensure they have the proper tools and experience.

Another consideration is availability. Not all technicians are familiar with DRL reprogramming, so you may need to call ahead or visit a specialized shop. Some owners report that dealerships are reluctant to disable DRLs due to liability concerns, so be prepared to explain your reasoning.

Is It Worth It?

If you value a factory-like finish and don’t mind the expense, professional reprogramming is the best option. It’s ideal for owners who want a permanent, hassle-free solution without DIY tinkering.

Legal and Safety Considerations

Before disabling your Infiniti Q50’s daytime running lights, it’s essential to understand the legal and safety implications. While DRLs are not federally mandated in the U.S., many states and countries have specific regulations.

U.S. Regulations

In the United States, the National Highway Traffic Safety Administration (NHTSA) does not require DRLs, but it encourages their use. Some states, like California and New York, have additional lighting laws that may affect your decision. For example, if your DRLs are part of a combined lighting system (e.g., they double as parking lights), disabling them could violate state codes.

International Laws

In Canada, DRLs are mandatory for all new vehicles. Disabling them could result in fines or failed inspections. Similarly, in the European Union, DRLs are required, and tampering with them may void your warranty or insurance coverage.

Safety Impact

Studies show that DRLs reduce daytime accidents by making vehicles more visible. The Insurance Institute for Highway Safety (IIHS) reports that DRLs can lower crash rates by up to 5.7%. Disabling them may increase your risk, especially in low-visibility conditions like fog, rain, or dawn/dusk.

Insurance and Warranty Concerns

Modifying your vehicle’s lighting system could affect your warranty or insurance policy. Some insurers view aftermarket modifications as increased risk, potentially leading to higher premiums or denied claims. Always inform your insurer if you make significant changes.

Maintenance and Troubleshooting Tips

After disabling your DRLs, it’s important to monitor your vehicle’s lighting system for any issues. Here are some tips to keep everything running smoothly.

Check for Warning Lights

After using any disable method, watch for dashboard warning lights. If the “Check Engine” or “Lighting System” light comes on, it may indicate a fault in the circuit. Use an OBD2 scanner to read error codes and address them promptly.

Test All Lighting Functions

Regularly test your headlights, brake lights, turn signals, and fog lights to ensure they’re working correctly. A malfunction in one area could indicate a wiring issue caused by your DRL modification.

Keep Records

If you use an aftermarket module or have the car reprogrammed, keep documentation of the change. This can help during service visits or resale.

Re-enable When Necessary

If you plan to drive in areas with strict lighting laws or during long trips, consider re-enabling the DRLs temporarily. This ensures compliance and maximizes safety.

Conclusion
