Реферат: The invention concerns an electronic circuit for dynamic command of light sources in variable message information panels. It includes a number of elementary circuits consecutively connected between them, each having at least one LED connected through respective switchable branches, to a feed voltage, to a LED short-circuiting line, to a contiguous elementary circuit and to a component or a control circuit output. Thus, by commanding the switching elements through the control circuit several elementary circuits can be selectively configured as closed circuits, each of which having a chain of LEDs activated in dynamically variable numbers wherein the feed voltage is applied to the feed branch of the first active LED of the chain and the control circuit output is closed on the last active LED of the activated LEDs chain.
