An electrical control circuit for a lighting and/or signaling module handling at least two functions from one and the same network of light sources of LED type. The function selection is handled by one or more input signals on the monitoring unit. If a branch or section connected to a defective LED fails, the monitoring unit can either deactivate all the branches or sections, or keep the remaining branches or sections active, and do so according to the function that is present. One or more functions can thus be compared to the single-section type despite the presence of a number of sections when the monitoring unit is configured to deactivate all the sections if one of the sections fails.
