The new vent register, used on the LEXUS UX, has LED illumination to improve the night visibility of the knob.
With a conventional wired power supply, the wire harness could break from repeated manipulations of the knob and other problems could occur. These issues are avoided with the application of a wireless power transfer technology.
The new register employs coupled mirrors within the lens of the LED light. This gives the ring of light an appearance of depth and creates a futuristic feel.
