Photo of the Ballast, Capacitor and Changeover Relay within the Philips/Idman IDM 7 A Dual Obstruction Light,

I am surprised the Ballast is made by Helvar, and is a Dual Wattage Ballast for either a 80 watt or 125 watt Mercury Lamp.

The Relay is Designed to automatically Switch over to the standby Light if the Main Light Fails to light.

Esmi was a Finnish manufacturer, now a part of Schneider Electric. They was some relays with special features, some of these is hard to find replacements.

This lantern is probably made in 2008. On the capacitor read week 44 2007 and the ballast date code means 345. day in 2007. This gear box is probably made by Finnish metal company Arsa Oy.
