Genesis EQ900 LED DRL Upgrade Review

Genesis EQ900 Daytime Running Lights: When Should They Turn Off?

The Genesis EQ900 features a unique daytime running light (DRL) design. While the bumper-integrated DRLs illuminate during the day, they automatically switch off the moment the headlights are activated. Many owners feel that having both sets of lights on simultaneously would significantly enhance the vehicle's premium appearance and safety. The solution to this common desire is the DRL constant-on upgrade.

Typically, vehicle lighting systems are designed so that DRLs dim or turn off when the headlights are engaged. However, the EQ900's DRLs completely extinguishing created a noticeable visual gap. This article details the DRL constant-on modification performed at Today's Car Anseong branch, illustrating how this upgrade transforms the EQ900's lighting.

How the Genesis EQ900 DRL Constant-On Upgrade Works

The core principle of the DRL constant-on upgrade is straightforward. By utilizing a module that detects the vehicle's light signals, the DRL power supply is maintained even when the headlight activation signal is received. This modification is performed internally through wiring, without requiring bumper removal, thus eliminating concerns about vehicle damage.

Installation Process:

1. Access wiring harnesses typically located under the dashboard or near the driver's footwell.
2. Identify and connect to the headlight signal wire and the DRL power supply wire.
3. Crucially, use an electronic module instead of a mechanical relay to avoid clicking noises and potential contact corrosion over time.
4. Integrate a discreet switch for toggling between the original and activated DRL states.

It's important to avoid using mechanical relays, as they can produce audible clicking sounds during operation and are prone to contact corrosion with prolonged use. Modern installations leverage electronic modules for silent, efficient power control.

Actual Results: Simultaneous Illumination of Both Light Sets

Post-installation, the DRLs remain illuminated even when the headlights are switched on. As seen in the visual examples, when the turn signal is activated, the opposite DRL continues to shine steadily. This not only creates a more luxurious aesthetic but also enhances safety by increasing the vehicle's visibility during nighttime driving.

A subtle, user-friendly switch is installed within the cabin to revert the system to its original state. This single-click switch allows seamless toggling between the stock and activated DRL modes. If you plan to sell the vehicle, returning it to its factory settings is effortless, preserving the car's value.

Genesis EQ900 DRL Activation: Cost and Difficulty

The DRL constant-on modification is considered a relatively simple tuning procedure. For domestic Genesis sedans, the average cost typically ranges from ₩300,000 to ₩500,000 (approximately $220-$370 USD). For imported vehicles, the price can range from ₩400,000 to ₩700,000 (approximately $300-$515 USD). Several factors influence the final price:

• Complexity of wiring specific to the vehicle model (e.g., Genesis vs. BMW vs. Porsche).
• Type of module used (electronic vs. mechanical, brand variations).
• Location and number of toggle switches for restoration.
• Labor rates at the specific installation facility.

The installation typically takes 1 to 2 hours, allowing for same-day completion with minimal waiting time. However, allowing the wiring to stabilize for at least 2-3 hours after the work is completed is recommended.

Who Should Get the EQ900 DRL Constant-On Upgrade?

This upgrade is particularly beneficial for owners who wish to fully appreciate Genesis's design philosophy. The EQ900 boasts a sophisticated lighting signature that truly shines with this modification. Additionally, drivers seeking enhanced road presence and a more premium look for their vehicle will find this upgrade highly satisfying. It's ideal for those who feel the stock DRL behavior is a missed opportunity for aesthetic and safety enhancement.
