Genesis EQ900 LED Upgrade Review: DRL Always On

Genesis EQ900: The DRL Dilemma

Many Genesis EQ900 owners notice a peculiar quirk: the striking LED daytime running lights (DRLs) on the bumper shine brightly when driving during the day. However, as soon as the headlights are activated in low-light conditions, these DRLs automatically switch off. This is a common point of dissatisfaction, especially when compared to many modern imported vehicles where DRLs either remain illuminated or dim to a lower setting, complementing the headlights. The EQ900's complete deactivation leaves owners wanting a more integrated lighting experience.

Fortunately, a solution exists to resolve this. The "Always On" DRL modification ensures your daytime running lights stay illuminated even when the headlights are on, providing a more premium and consistent aesthetic. This upgrade can be achieved without the need to remove the front bumper, making the process efficient and safe.

Understanding the EQ900's Lighting System

The Genesis EQ900, as a flagship luxury sedan, features a sophisticated LED lighting design. The DRLs are distinct units located in the bumper, intentionally wired to operate independently from the main headlights. The automatic deactivation when headlights are switched on is a direct result of this specific circuit design. While the original intent might have been to prevent light scatter and ensure optimal headlight performance, the trend in contemporary vehicles leans towards maintaining DRL illumination for enhanced visibility and a modern appearance.

The LED Upgrade Process: Seamless Integration

This lighting modification is performed without removing the front bumper, significantly reducing the risk of damage and speeding up the installation. Technicians access the necessary wiring from underneath the vehicle to install a specialized control module directly into the DRL circuit. This module utilizes an electronic control unit rather than a mechanical relay. This is crucial because mechanical relays can produce audible clicking sounds during operation, whereas the electronic module works silently, ensuring a disturbance-free driving experience.

Installation Details and Timeframe

The entire process typically takes around 1 hour to complete. Because the bumper is not removed, there is minimal waiting time, and the vehicle is usually ready for immediate use after the service. The car is safely elevated on a lift during the procedure, and all electrical connections are treated with waterproof coating to prevent moisture ingress and ensure long-term reliability.

Post-Upgrade Lighting Behavior

After the modification, the EQ900's lighting system operates with enhanced functionality. The DRLs on both sides of the bumper remain illuminated when the headlights are switched on. An interesting change also occurs when the turn signals are activated: the DRL on the side of the active turn signal will flash accordingly, while the DRL on the opposite side continues to emit a steady light. This mimics the behavior of DRLs in many high-end imported vehicles, adding to the car's premium feel and improving safety through increased visibility.

User Control and Reversibility

A key feature of this upgrade is the inclusion of an interior switch, typically installed in the driver's side footwell. This discreet switch allows the owner to toggle between the "Always On" DRL mode and the original factory setting (where DRLs turn off with headlights) at any time. This provides complete flexibility, allowing owners to revert to the stock configuration if desired, such as when selling the vehicle or for personal preference, without any permanent alterations.

Safety and Electrical Integrity

Concerns about electrical load and safety are paramount. The control module is designed to integrate seamlessly with the vehicle's existing electrical system, drawing minimal additional power and ensuring that the DRLs operate within safe parameters. The waterproof treatment of all connections further guarantees the longevity and reliability of the modification, protecting against environmental factors.
