Unprecedented technology uses optical engineering to change cabin decoration and reinforces the 'living room' trend in vehicles
Toyoda Gosei, a subsidiary of the Toyota group specializing in automotive components, has launched a new ambient lighting technology capable of projecting moving light patterns into the interior of vehicles. The system, dubbed LED Shadow Light, makes its commercial debut in the Lexus RZ, the luxury brand’s first SUV dedicated exclusively to electric propulsion.
Unlike traditional ambient lights, which only emit static colors, the innovation uses precision optical engineering to manipulate shadows and light. The compact module houses multiple LEDs that, when activated alternately, modify the incidence of light on textured lenses. The result is the projection of geometric and animated designs on the door panels, creating a sense of depth and movement.

According to the supplier, the development of the technology responds to a growing demand from the automotive sector: to transform the cabin into a living space. With the rise of electric cars and the evolution of autonomous driving, the focus of automakers shifts from mechanics to user experience (UX), where lighting plays a crucial role in visual comfort and relaxation for occupants.
The feature is available on the most sophisticated versions of the Lexus RZ, including the F Sport configuration. The model also serves as a showcase for another Toyoda Gosei technical collaboration: the joystick steering wheel (Yoke).
Although the steer-by-wire steering system (which eliminates the mechanical connection between the steering wheel and the wheels) is a complex architecture, it was up to Toyoda Gosei to develop the compact airbag module and steering wheel rim specifically for this shape. The piece had to be redesigned to integrate
