Many vehicles on the road today offer ambient cabin lighting, and Ford vehicles have offered customizable ambient light colors for some time. The 2012 Ford Focus' cabin has this customizable LED ambient lighting setup, but also includes a few new features that add quite a bit of functionality to what was once just a styling option.
A new mode called "search light" allows users to, at the touch of a button, change the lighting color to white and increase the brightness of door, footwell, and cupholder lights to help quickly find dropped items. Sure, cars have had dome lights for ages, but this mode puts the light where it's needed: down in the vehicle's nooks and crannies. There are also new two-stage welcome and exit lighting programs and a door ajar program that causes the door illumination to glow bright red when the door is open to serve both as a warning to approaching motorists and cyclists, as well as to the occupants in the event of improper door closing.
Additionally, a feature called "play protection" acts as a sort of child lock for the interior lighting, preventing children from operating the dome light and ensuring that the interior lighting isn't accidentally left powered on, unnecessarily draining the vehicle's battery.
