Abstract
A road-marking system comprising at least a first (1) and a second road marking unit (2), each having an emission surface (10; 20), the first unit comprising a first light source (21, 21′ . . . ) and the second unit comprising a second light source (22, 22′ . . . ). Each unit has a housing (11, 12) of a shape adapted to a saw-cut cavity (9) accommodating the unit and lying in a plane P. Each unit is provided with stabilizers (23, 23′; 24, 24′) which are situated at the ends of said emission surface and lie in the plane P as well, thus preventing turning of the unit around an axis A normal to the plane P.
