Communication, Without Electronics.

Express Your Style

The Signal Speak® Butterfly Tail-Light Overlay is a removable decorative tail light cover overlay that is part of our patent-pending non-electronic Vehicle Communication System.

Designed to express your personality and style, the Butterfly Overlay transforms your existing tail lights into a unique visual expression using the light your vehicle already produces.

Unlike electronic message boards or distracting digital displays, Signal Speak uses your vehicle's existing lighting. No wiring. No batteries. No Bluetooth. No vehicle modifications.
