Each dual view module comprises of a forward and rear image lens and a forward and rear illumination bulb. Each dual view module is designed and attached to the shaft in a way that when deployed, the forward image lens and the forward illumination bulb face forwards and provide forward view; and the rear image lens and the rear illumination bulb face backwards and provide rear view. An actuator is used to selectively move the housings from a first non-deployed position to a second deployed position.
