The optical warning system has a luminous longitudinal ramp (70,80) with three planes having two outer colors and a central color in opposition. Five lighting combinations are possible forming different warning lights. One light is standby, and others represent different road warning alerts set by a keyboard switch. There is a low luminosity warning light at the keyboard center.
