An aviation warning light installation is a set of lamps and a control cabinet. The lamps sit where the rules require them: at the top of the structure and, on a tall one, at intermediate levels as well. The cabinet at the foot holds the power supply, the control and the connection that carries status away from the site. Red lamps switch on by themselves at night, as the current rules require, so there is nothing for anyone to remember and nobody to send up the structure at dusk.
Establish what the structure requires: its height, its position and the rule that applies
Set the lamp positions, the intensity and the day and night behaviour
Install the cabinet, the supply and the connection that carries the status
Bring the installation onto the platform, so a dark lamp is seen the same day
