An edge profile for bordering the superstructure of a rescue vehicle is contemplated, specifically an edge profile for bordering the upper walking deck of a firefighting vehicle that provide a modular construction system with enhanced security features. The edge profile is an extruded hollow body having a cross section with a front wall portion and an upper and lower groove for simultaneously illuminating the border of the upper walking deck and the environment around the base of the vehicle. The edge profile modularly engages with the vehicle body via cross-sectional horizontal and vertical mounting grooves, which do not require welding. A lower flange portion is further provided to cover upper parts of storage compartments at the sides of the vehicle, especially roller shutters.
