Mazda Designed LED Turn Signals That Emulate The Human Heartbeat

“I wanted to embody Jinba Ittai-the intuitive connection between car and driver-so that even the act of making one turn of the wheel is a human-centric experience,” he says. He also explains how by reinventing the turn signal, Mazda wanted to induce feelings of calm and safety for pedestrians seeing cars approaching with their turn signals on. According to Yoshida-san, he “focused on how a driver’s intention emanates from their heart, extending to their heartbeat and pulse.” Then, he and the design team used an electrocardiogram to analyze the human heartbeat. “I watched heartbeat waveforms undulate, linger and diminish, resulting in a turn signal that expresses the warmth lacking in LED lamps.”

The team faced some problems during development, though. The concept was originally scheduled for installation on the Mazda 3, but Mazda struggled with inconsistent dimming. Mazda had to work with its supplier to adjust the timing in increments of 0.01 seconds before finding the perfect timing. It was only then that DTS could be installed on the CX-30.
