By adjusting the brightness of Edison lamps using a dimmer circuit, the illumination of the GU-10 radio lamp (for entourage with horns) shimmers in different colors.

Two backup voltmeters: analog and digital.

On the sides of the box there is a regular 220V outlet and a phone charger with 2 USB inputs

On top is a small LED lamp in a black case, which is also turned on by a toggle switch. This is a real army box from the 60s.

Power is supplied from the key, as in a car ignition lock.
