I have recently acquired a 1930s Sterling sirenlite which will be going on my Deuce and a half. It is 6 volt and works great but the bulb has blown. It is an old GE type with no markings on it whatsoever. Does anyone know what wattage it should be?
This came my way from the US last week and is going to be fitted soon. Going by an old Airfield photograph at Kimbolton it should look good.
