Abstract: A luminous safety device for vehicle doors which includes a push-pull button of electrical insulating material, the head having transparent walls and a sleeve portion connected to an actuating rod of the door-locking mechanism, said rod being connected to ground and making contact with one of the poles of a lamp placed within the interior of the head of the button, said lamp having its other pole connected to an electrically conducting ring mounted on the outer surface of the sleeve portion of the button, said ring making contact with a conducting projection inserted in an insulating shell which surrounds the button and which is secured by its upper edge in the orifice in the door in which the actuating button slides; and because the conducting projection is connected to a source of energy, when the button is pulled and contact is made between the button conducting ring and the conducting projection the lamp is energized and lights, indicating clearly that the door-locking safety has not been engaged.
