Taxi Rooftop Digital Signs are a great way to spread advertising messages by bringing attention to a message tailored to a specific market sector group. The message increases sales and brand awareness for the advertisers products or services. The MEAD 4 which is an LED P4 display is connected to a main server that will receive any change to a content through its embedded Android player which in turn is connected through wireless 4G / 5G connection, including a GPS tracking module keeping every vehicle in track of where its content is being published. Our illuminated two sided LED Taxi Rooftop Digital Sign is an excellent opportunity for the Taxi Company entrepreneur who is looking to enter into the Advertising market and generate more income to their fleet of taxis. The installation and removal of our Taxi Rooftop digital sign is simple and a manual if provided with 24 hours live support.
