sasecgo Devil Eyes LED Windscreen Sign 2-Pack — Programmable Bluetooth RGB, Flexible Scrolling Display

sasecgo Devil Eyes are a pair of thin, flexible RGB LED windshield signs that display animated eyes, custom text, graffiti and scrolling effects controlled from your phone.

These two compact LED matrices attach with double-sided tape and run from USB power to add eye-catching, programmable lighting to cars, trucks, or any windowed surface. The signs connect by Bluetooth to the CoolLED1248 app, where dozens of built-in patterns, speed and brightness controls, and a text/animation editor let you craft personalized visuals. The panels are lightweight and bendable, so they conform to curved glass or dashboard spaces and store easily when not in use.

How do I set up the Devil Eyes on my vehicle?

Installation is straightforward and requires no special tools: peel the adhesive, position the thin LED panel on the inside of a window, and plug the included USB cable into a power source. Pairing with the app is done over Bluetooth and the app walks you through linking two panels simultaneously for synchronized effects.

• Included: two LED sign panels, double-sided tape, two 14.7 ft USB cables.
• Mount inside windshield or other smooth surfaces with supplied tape.
• Pair panels via Bluetooth in the CoolLED1248 app for synchronized displays.
• Power from any USB port or 12V adapter with USB output.

What customization can I create with the app?

The CoolLED1248 app provides a library of preloaded eye animations, plus tools to draw graffiti, edit scrolling text, and design frame-by-frame animations. You can tweak brightness, animation speed and display modes to match daytime or night use, and save custom presets for quick recall.

• Choose from built-in eye animations and lighting effects.
• Create custom text banners, symbols, and animated frames.
• Adjust RGB brightness and pixel speed for visibility balance.
• Save and update new patterns as the app receives updates.

Will the panels fit curved windshields and travel without damage?

The panels use a flexible board and RGB lamp beads, allowing light panels to bend and conform to slight curves without breaking. Their thin, foldable design also makes them easy to remove and stow between uses while minimizing pressure on curved glass.

• Flexible PCB construction tolerates gentle bending and folding.
• Lightweight materials reduce strain on mounting surfaces.
• Thin profile stays discreet when installed behind glass.
• Detachable design for simple storage or re-positioning.

Who is this for? Drivers, vehicle enthusiasts and creators who want a highly visible, customizable visual accent — from show cars and trucks to promotional or novelty applications. If you want an easy-to-install, app-driven LED sign that can display animated eyes, custom text, or hand-drawn graffiti and is portable enough to move between vehicles, this two-piece saged set from sasecgo gives you full creative control without complicated wiring. It’s ideal for people who value visual customization, night-time presence, or temporary installations that are simple to update through a smartphone app.
