Mopti-Fi由兩大核心組件構成：包含數條可伸縮光纖警示燈條，以及外部連動機構。一端固定於車頂，另一端則透過感測器偵測路面狀況，自動延伸至路面之指定距離。此設計旨在縮短使用者手動擺放警示標誌的時間，增加後方來車的反應距離，並藉由大面積照明屏障，達成對接近車輛之有效警示作用。

Mopti-Fi consists of two main components: an internal unit containing several retractable fiber optic warning light strips and an external mechanism. One end of the light strips is fixed to the vehicle roof, while the other end automatically extends to a designated distance on the road surface, guided by sensors that detect road conditions. This design reduces the time required for users to manually place warning signs, increases the reaction distance for oncoming traffic, and forms a large illuminated barrier to effectively warn approaching vehicles.
