- Patents are known, on rearview mirror assemblies with a turn signal emitted in three directions forward, side and rear. To produce these signal emission directions, these mirrors have a single light module or device that emits through a window closed by an external transparent cover that extends from the front, opposite the main moon, to the far end of the body, where they have a projection, unevenness or a shape that allows the light to be emitted back and side.
- Signal devices located at the bottom and below the mirror line are known, US 5,371,659 position that increases the volume of the housing, air resistance, fuel consumption and the part that emits light back is visible by The eyes of the driver. Therefore, we focus on devices that emit a signal backwards from the far end of the body that occupy an interior volume behind the moon in said rear-view mirror assembly.
- the protrusion of the transparent coincides with the lateral protrusion area of the vehicle capable of receiving collisions.
- Each mirror has an external curve and a different shape, this prevents standardizing parts for reuse in different vehicles; and it implies more development time, cost of molds, more parts and tools.
