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.
