The aerosol-generating device comprises: control electronics; a substantially linear first lighting array and a substantially linear second lighting array. Each of the first and second lighting arrays extend over a length between first and second ends of the respective lighting array. The control electronics are coupled to the first and second lighting arrays and configured to activate either or both of the first and second lighting arrays to generate a predetermined light emission indicative of and in response to at least one of: i) a status of the aerosol-generating device; and ii) progression of an operational phase of the aerosol-generating device.
