A light-emitting device, especially for lighting and/or signaling for a motor vehicle, includes at least a first electroluminescent module and a second electroluminescent module energized in series. Each electroluminescent module includes, in parallel: a first branch having a light source having a first direct threshold voltage beyond which the light source is gated on, and a second branch having an element such that the voltage on the terminals of the element is less than the first direct threshold voltage of the light source. A third branch has a timing module able to time a predetermined period and modify, at the end of the predetermined period, an overall impedance of the second branch so that a voltage in the second branch is greater than the first direct threshold voltage of the light source. The predetermined period in the first electroluminescent module is less than that of the second electroluminescent module.
