Using the lighting system as a welcome feature is another obvious novelty this system could facilitate, but it could also act as a reminder when you exit the car. The documentation explains: “Upon turning off and exiting the vehicle, a farewell feature will function. In the event the key fob is left in the vehicle and the vehicle is locked [using a keyless entry system, an app, or the SecuriCode keypad], the light source can blink alternately between red and white and a horn of the vehicle will sound until the key fob is retrieved from the vehicle.”
The system is said to be scalable, and the design “is also flexible for rear applique covers,” suggesting that it’s viable for use on future production cars. Notably, the system could be adapted to traditional grilles, which means we may see its use on hybrid Lincolns or gas-powered Fords too.
