Taxi Rooftop Digital Signs are a great way to spread advertising messages by drawing attention to a message that is tailored to a specific market sector group. The message boosts sales and raises brand awareness for the advertiser's goods or services. The MEAD 4, an LED P4 display with 5000 nits brightness, is linked to a main server, which receives any changes to content via its embedded Android player, which in turn is linked via a wireless 4G or 5G connection, as well as a GPS tracking module, which keeps each vehicle track of where its content is published. Our illuminated, two-sided LED taxi rooftop digital sign is an excellent opportunity for the taxi company entrepreneur who is looking to enter the advertising market and generate more income for their fleet of taxis. The installation and removal of our Taxi Rooftop digital sign are simple, with 24 hour live support provided.
