Illuminating device for RRH sound locator

[Dufleuve]

Hello,

Here is a funny device I could not identify for a while.
A illuminating device to allow the RRH sound locator operator to see the elevation scale at night. The cylindrical body contains a small socket and the bottom is closed by a kind of transparent plexiglas screen. The Aus-Ein switch on top is linked to the RRH power source. There is a faint WaA proof on the side of the Ein mark.
