Outline marker lamp or park lamp

The invention relates to an outline marker lamp or a park lamp, which is designed for lighting lories and their full and semi-trailers, by front, side, rear outline marker light or a park light, and consists of a body sealed from the front end by a lens, wherein a set of electroluminescent diodes and electrical supply circuit are located. The lamp is characterized in that electroluminescent diodes (3) are connected to a circuit (5) for lighting the diodes in a sequential order, where said circuit works as a power supply for the lamp, and said electroluminescent diodes (3) in the lamp body are arranged around the perimeter of an oval or tetragonal or triangular geometric figure. Preferably, the circuit (5) for lighting the diodes in a sequential order is a circuit for cyclical lighting the diodes in a sequential order, and the diodes (3) in the lamp body (2) are evenly spaced apart.
