Abstract: Disclosed is a device for displaying an instruction by a B14 or equivalent panel having a flat circular front plate with an instruction display area. In the case of a B14 panel, the digital value displayed can be modified by changing at least one modifiable character. The display area includes an opening and the panel includes at least one flat movable support on which the substitution figures are represented, the front plate and the flat movable support being parallel to each other, the flat movable support being included in the template of the front plate, each substitution figure being provided by an actuator facing the opening, the flat movable support or at least one of the flat movable support being a rotatable disc, the centre of the rotatable disc being laterally offset with respect to the centre of the circular front plate. The device is autonomous with photovoltaic power supply.

Abstract: The structure (10) of light display for vehicle traffic lane(s) is of the type including at least one vertical support post (7), a substantially horizontal crossbar (3) fixed high to said at least one support post (7) and a variable-message light display panel (2) fixed to said crossbar, said display panel (2) having a front face on which the light messages are broadcast, and a rear face, said display panel being elongated along the crossbar (3), parallel and fixed to the latter, said structure including an autonomous electric power supply source comprising at least one photovoltaic panel (1).
