Leadleds P2.5 Dual-Sided LED Car Roof Sign 38in | WiFi 4G GPS | Waterproof

Who This Product Is For This display is built for business operators who need reliable, high-visibility mobile advertising: taxi and rideshare fleet owners, food truck operators, delivery companies, contractors, event marketing teams, and fleet managers who need to update messages across multiple vehicles remotely. It solves three specific problems: low visibility of static roof signs in daylight, inability to change advertising content without visiting the vehicle, and lack of vehicle location tracking for fleet operators.

The built-in ambient light sensor automatically adjusts brightness based on surrounding conditions, reducing power draw at night without manual intervention. IP65 Waterproof and Shock-Resistant Construction The metal frame and IP65-rated enclosure protect internal components from rain, dust, and road vibration. The cabinet profile is 70mm at its thickest point, reducing wind resistance at highway speeds. Total cabinet weight is approximately 23 kg. WiFi Local Control (iOS and Android) Connect via WiFi within approximately 30 ft of the vehicle to push new messages using the iOS or Android app. No external Wi-Fi needed, no monthly fee. 4G Cloud Remote Control With the 4G cloud option, update display content from any location with internet access. Manage single or multiple vehicles from one web-based dashboard. No on-site visit required to change advertising copy. Built-In GPS Tracking and Geo-Fencing (GPS Cloud variant) The GPS Cloud variant adds real-time vehicle location tracking via a mobile app. Geo-fencing allows you to assign specific messages to display only when a vehicle enters a defined geographic zone. For example, a food truck can automatically show a location-specific promotion when it enters a stadium district, or a delivery vehicle can display a neighborhood-specific message when entering a customer zone. Typical Applications Taxi and Rideshare Fleets: Display rotating advertisements or service announcements. Update content remotely across the entire fleet from a central dashboard. Food Trucks: Show current menu items, location, or promotions. Change content between locations without stopping operations. Delivery and Logistics: Display delivery status messages or company branding. Fleet managers can update driver-facing or public-facing messages remotely. Contractors and Service Vehicles: Display DOT-compliant safety warnings or service promotions while in transit.
