sasecgo Programmable LED Car Sign RGB Flexible Panel — Bluetooth App, 14.7ft USB Cable

The sasecgo Programmable LED Car Sign is a flexible RGB matrix panel that scrolls custom messages and animations via a Bluetooth phone app for indoor and in-vehicle displays.

Whether you want to promote a business, decorate for events, or add creative messaging to your vehicle, this lightweight LED board lets you design text, graffiti, and motion effects from your phone. The CoolLED1248 app connects by Bluetooth and includes a library of patterns that receive ongoing updates, while controls let you tweak brightness, speed, and display mode. The panel uses RGB lamp beads on a bendable substrate and installs quickly with 3M tape and a long USB power cable.

How do I create and change messages with the app?

Connect your phone to the sign using Bluetooth, open the CoolLED1248 app, and use the built-in custom editor to type text, draw graffiti, or assemble frame-by-frame animations. You can save presets and recall them instantly.

• Bluetooth pairing for quick device link
• Text, handwriting, and animation editor inside the app
• Adjustable scroll speed and multiple display modes
• Save, rename, and manage message presets

What installation and power options are available?

The sign ships with 3M double-sided tape for secure mounting and a 14.7-foot USB cable so you can reach a power source inside most cars or indoor settings. The lightweight, thin panel adheres flat or around gentle curves.

• 3M tape for quick stick-on mounting to windows or surfaces
• Long USB cable (14.7 ft) for flexible power placement

How durable and portable is the LED panel?

The matriz-style board is designed to be both light and bendable, made with RGB lamp beads on a flexible substrate so you can fold or curve the sign for installation around rounded surfaces. It’s optimized for indoor or in-vehicle use rather than continuous outdoor exposure.

• Thin, lightweight profile for easy carrying and storage
• Best suited for indoor, car-window, or sheltered displays
