XIAOOHO Devil Eyes LED Car Windshield Display — 2pcs Programmable RGB Panels, Bluetooth App Control

XIAOOHO 2-piece programmable Devil Eyes LED signs are flexible, USB-powered displays for windshields that show synchronized eye graphics, editable text, graffiti and animations via Bluetooth app control.

These compact LED boards mount inside car or truck windshields to add a striking visual accent while you drive or park. Each set contains two slim, bendable panels with bright RGB LEDs and long USB leads that plug into a 5V source. Using the free app you can pick preloaded patterns or design your own short messages, drawings and animated sequences, then synchronize both signs for a coordinated effect.

How do the Devil Eyes lights connect and synchronize?

Connection is handled over Bluetooth from your phone to each sign. Once paired, the app can link the two panels so they display the same animation or complementary sequences in perfect sync.

• Bluetooth pairing for quick setup without extra wiring
• Dual-device sync to run identical or matched displays
• Long USB cable (about 14.7 ft) for flexible placement and power
• Works with standard 5V USB power sources for low heat operation

What customization options are available in the app?

The companion app offers multiple built-in eye animations and an editor for freehand graffiti, text messages and frame-by-frame animations. You can fine-tune color, speed, brightness and display modes from the same interface.

• Choose from preset Devil Eyes animations for quick setup
• Create short text or hand-drawn graphics using the built-in editor
• Adjust RGB colors, animation speed and overall brightness
• Save custom scenes to reuse or schedule later

How is the product built for vehicle use?

The signs use high-density RGB LEDs on a flexible substrate so panels conform to curved windshields and interior glass. The thin form factor and low-voltage USB design minimize heat while keeping the display visible in low-light conditions.

• Flexible board design bends to match glass curvature
• 2121 RGB LED bead array for clear, colorful output
• Low-voltage 5V USB power reduces heat and power draw
• Lightweight panels that install without heavy brackets

Are there practical tips for installation and use?

Place the panels on the inside of the windshield or rear window, keeping USB cables routed safely to a 5V outlet or power bank. Secure placement and correct orientation maximize visibility and prevent glare for the driver.

• Mount inside the windshield using tape or Velcro where permitted
• Run USB cables along trim to avoid obstructing controls or view
• Choose brightness levels appropriate for daytime vs. night use
• Check local regulations about interior displays before use

Who is this for? The XIAOOHO Devil Eyes programmable LED signs suit car and truck owners who want a customizable, eye-catching interior display—enthusiasts, show-car hobbyists and anyone who enjoys personalizing their vehicle’s look. They’re also a good match for drivers who need a flexible, low-heat solution that can be edited on the fly via smartphone for events, meetups or promotional displays.
