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.
