Abstract
There is described a system and method for informing passengers of a public transport vehicle of a door lock status, the method comprising: optically coupling a light source to an at least partially see-through modesty panel for propagating light therein, the modesty panel being positioned within the transport vehicle adjacent to a door for separating the passengers from the door; receiving a signal indicating that the door is unlocked; and illuminating at least a portion of the modesty panel using the light source, thereby informing the passengers that the door is unlocked.
