A flap mechanism (2) has a housing (10), a flap aperture (21) formed on the housing (10), and a flap element (20) that at least partially closes the flap aperture (21) in a closed position and can be transferred from the closed position to an open position for at least partially freeing the flap aperture. The flap element (20), in the open position, protrudes at least with an end portion (200) from the housing (10). At least one light element (22) is arranged on the flap element (20) and generates a gleam of light on the end portion (200) of the flap element (20) at least in the open position of the flap element (20).
