Mercedes-Benz has announced the use of turquoise LED daytime running lights to signify the activation of its level-three autonomous driving technology, Drive Pilot, in the United States. This groundbreaking technology has received approval for use on public roads in California and Nevada, marking a significant milestone in the integration of autonomous systems into everyday driving.
Mercedes’ Drive Pilot is an optional lidar-based system, which features in the S-Class and EQS models to navigate autonomously at speeds up to 40 mph. This technology ensures the vehicle stays within its lane, dynamically adjusts its distance from the vehicle ahead, recognises traffic signs, and autonomously performs evasive manoeuvres. According to the standards set by the engineering organisation SAE International, Drive Pilot achieves the first level of autonomy, where human intervention is not required for driving tasks.
With Drive Pilot engaged, drivers can temporarily relinquish control, allowing them to engage in secondary activities like browsing infotainment displays or managing emails. However, the system mandates the driver’s readiness to resume control in adverse conditions such as unfavourable weather conditions. In the event of a driver not responding promptly to take over, the car initiates an emergency procedure, coming to a standstill, activating hazard lights, and unlocking the doors.
A notable feature accompanying the introduction of Drive Pilot is the use of turquoise LED lights – a first in the automotive industry. These lights serve as a clear signal to other road users that the vehicle is operating in autonomous mode. Mercedes-Benz opted for turquoise due to its visibility and distinctiveness from conventional traffic signals and vehicle lighting. The turquoise lights can be seen in both the headlights and tail lights, clearly indicating the Drive Pilot mode to other road users.
Speaking of its benefits, Mercedes envisions broader applications for the turquoise LED lights, particularly in aiding law enforcement. Police officers could more easily identify vehicles in autonomous mode, ensuring drivers are not distracted by other activities when they should be in control.
In California, the turquoise LED lights have received approval for a two-year testing phase, showcasing the commitment to rigorous evaluation and refinement. In Nevada, the lights are set to become legally permissible on production cars in 2026. Recently, Mercedes-Benz was also granted permission to test its autonomous driving tech on Beijing highways in China.
