The invention relates to a lighting installation, for instance, airport orroad navigation lights, obstacle warning lights, advisory, warning and signallights or the like, comprising a device for monitoring, controlling andregulating its light sources (4) or groups of light sources (4), each of whichhas at least one light unit (10) that is allocated to a send-receive device(3) with a microcontroller, which is connected by a power supply line (6) anda router (8) to a central unit (2) having a send-receive section and a controlcomputer, and which can be impinged upon by control signals therefrom. Inorder to safely and reliably operate large-sized lighting installations havinga plurality of light sources that are controlled and regulated differentlywith comparatively little complexity, the microcontrollers of each light unit(10) are components of a decentralized control unit (3) having application-specific components such a switching, monitoring and regulating elements.
