This utility model relates to an externally mounted three-dimensional illuminated lettering and an automobile, belonging to the technical field of externally mounted illuminated lettering. It includes a base cover and a lampshade, with an installation space between the base cover and the lampshade. A circuit board is housed within the installation space, and an LED module is encapsulated on the circuit board. The inner surface of the lampshade has laser-engraved character boundaries; the area within the character boundaries is a light-transmitting area, and the area outside the character boundaries is an opaque area. Light emitted by the LED module passes through the light-transmitting area. By placing the circuit board and LED module inside the base cover and lampshade, and driving them via an externally located driving circuit through electrical connections, the overall size and height of the lettering are reduced, meeting the requirement that the external protrusion height of the automobile is ≤10mm. The lettering is designed separately and can be assembled externally, saving installation space and offering a high degree of assembly flexibility. Even when not illuminated, the laser-engraved character boundaries still have a three-dimensional effect; when illuminated, the light-transmitting area allows light to pass through, thereby improving the lettering's recognition effect.
