- FIG. 7b shows in front view (outer side side 12 ') the male spoke side.
- These patterns 8a, 8b are permanent on the outer face 12, for example textured (sandblasted, frosted, etc.), face opposite to the inner face covered by the first reflecting layer, preferably mirror, by silvering with its protective paint.
- These patterns 8'a, 8'b are permanent on the outer surface, for example textured (sandblasted, frosted, etc.), face opposite to the inner face covered by the second reflecting layer, preferably mirror, by a silvering with its protective paint .
- the woman's side is offset from the male side of D
- the color of the patterns on the female side can be distinct from that on the men's side. On either side this color can be static or dynamic.
- removable extraction means such as erasable stickers or ink on the outer face 12 ', for example vertically and peripherally (to keep the mirror function) four symbols 8'c to 8'f (tie, shirt, trousers, jacket) white or colored (matching the colors of diodes coupled to the second glazing) associated with a percentage of reduction 81 'to 84'.
- the symbols and / or the associated percentages are not necessarily of the same color. From one radius to another, the symbols and / or the associated percentages are not necessarily of the same color or illuminated by the same color at a given time t0.
