Genesis EQ900 Lighting Upgrade Review: Enhanced Visibility

Genesis EQ900 Daytime Running Light (DRL) Always-On Mod

The Genesis EQ900, now known as the G90, boasts a distinctive long, slim daytime running light design that contributes to its grand aesthetic. However, in its stock configuration, the DRLs are designed to dim or switch off entirely when the main headlights are activated. This is a legal requirement but can leave the front of the vehicle feeling less prominent, especially during nighttime driving or in adverse weather conditions. This modification aims to keep the DRLs illuminated at full brightness even when the headlights are on, enhancing the car's visual presence and perceived grandeur.

Understanding the Stock DRL Behavior

In its original state, the Genesis EQ900's DRLs serve a dual purpose. During the day, they activate with the ignition, signaling the car's presence. Yet, when the headlights are engaged, their intensity is reduced or they turn off completely. This is a standard compliance feature across many vehicles. Furthermore, when the turn signals are activated, the DRLs temporarily extinguish to allow the amber turn signal lights to be the sole illumination on that side of the front fascia. While functionally correct, this can diminish the striking visual signature of the EQ900's signature lighting, making it appear less distinctive in low-light scenarios.

The Always-On DRL Upgrade: What Changes?

The 'always-on' DRL modification ensures that the signature white DRLs remain fully illuminated alongside the headlights. This upgrade doesn't just increase brightness; it enhances the vehicle's visual appeal by maintaining a consistent and striking front-end appearance. Unlike high beams, this modification is designed not to cause glare for oncoming drivers. The result is a more substantial and visually complete front profile, particularly beneficial for vehicles that may not feature prominent fog lights. The system is engineered to revert to standard operation when turn signals are engaged, ensuring safety and compliance are not compromised. This modification effectively boosts the aesthetic appeal while adhering to safety regulations.

Installation Process:

1. An additional module is integrated into the vehicle's lighting system.
2. This module modifies the DRL signal to remain active when the headlights are switched on.
3. The system is tested to ensure correct operation, including the reversion to standard DRL behavior when turn signals are activated.

Considerations for the EQ900 DRL Mod

When considering this upgrade for a premium vehicle like the Genesis EQ900, the type of module used is crucial. Modules are generally categorized as mechanical or electronic. Given the exceptionally quiet cabin of the EQ900, a mechanical module might introduce an audible 'click' sound when the turn signals deactivate and the DRLs return to their always-on state. Electronic modules typically offer a more seamless and silent operation, making them a preferred choice for luxury vehicles where cabin acoustics are paramount. The estimated cost for this type of modification in Korea is under ₩50,000 (approximately under $40 USD), depending on the module chosen and the installer.
