A baseball cap (or other brimmed hat) with a one-line display screen that hangs down at the edge of the brim. Text scrolls along from right-to-left at a variable selectable speed. The screen might fold up under the brim when not in use. *pulls hat down a little more*

Only if it scrolls "Escaped Mental Patient...Extremely Violent...Avoid Eye Contact" then it flickers and gives you a little shock so that it causes one of your eyes to blink.

Or "HELP ME... I am mute...Which way to the bus station?"
