Spherical stylized traffic light design 1

This is the 3D model of design 1 of a stylized traffic light.
The basic idea was to design the light fixtures and the button in a spherical shape.
The model has a height of 4 meters.
To make inserting and moving the model in a 3D scene as easy as possible, the lower center of the bounding box was chosen as the insertion point (object origin).
The model has no textures, only material settings.
