Renault Grand Koleos Ambient Lighting Review — Cost & Results

Renault Grand Koleos: Addressing the Stock Ambient Lighting Gap

Many Renault Grand Koleos owners find the factory-installed ambient lighting to be somewhat lacking. While present, it's often limited to small sections of the front doors, leaving the overall cabin atmosphere feeling incomplete, especially during nighttime drives. If you're looking to enhance your Grand Koleos' interior ambiance beyond the standard offering, a custom ambient lighting retrofit can be an excellent solution.

Custom Ambient Lighting Installation for Enhanced Ambiance

This review focuses on a custom ambient lighting setup for the Renault Grand Koleos, comprising a base package (dashboard lines) and optional additions like footwell lights for the front and rear seats. Due to the complexity of non-visible installations in this model, an exposed acrylic ambient lighting method was employed. While direct integration with the car's native modules might still be under development or require external modules, a Bluetooth control system offers extensive control over colors and brightness. The estimated cost for this type of upgrade in Korea is under ₩400,000 (approximately under $300 USD, though actual US pricing may vary significantly). This system automatically powers on with the ignition, mirroring the convenience of factory options.

The dashboard lines were installed on either side of the steering wheel. While extending this to the door panels could create an even more immersive feel, the dashboard lines alone provide a significant upgrade, especially considering the existing stock lighting. Aftermarket ambient lighting systems offer a much wider spectrum of colors compared to factory options, and the Bluetooth control makes selecting your preferred hue effortless. For this particular installation, the owner opted for a striking blue.

Installation Process:

1. Component Placement: Acrylic light guides are carefully positioned along the dashboard lines and within the footwell areas.
2. Wiring and Connection: Wires are discreetly routed and connected to the Bluetooth control module and power source.
3. Module Integration: The Bluetooth module is set up for easy pairing with a smartphone.
4. Testing and Calibration: Lights are tested for functionality, brightness, and color accuracy, with adjustments made as needed.

Adding Footwell Lighting for a Softer Glow

A key enhancement in this setup is the addition of footwell lighting for both the first and second rows. This is particularly beneficial for drivers who find the floor area too dark at night, improving both aesthetics and safety. The second row, often lacking any factory ambient lighting, sees a substantial improvement in cabin atmosphere with just the addition of footwell lights. These lights utilize custom acrylic pieces for a clean, integrated look, appearing natural even when off. When illuminated, they provide a subtle yet sophisticated ambiance, with brightness levels adjustable to preference. Even at maximum brightness, using around 20% of its capacity is often sufficient, creating a pleasant glow that effectively illuminates the floor space, especially impactful in the second row due to the higher seating position.
