LED Sign turns your phone into a handheld LED marquee — a glowing message you hold up so the right person sees you.
Whether you're cheering at a concert, picking someone up at the airport, proposing under the stars, or just need to be seen in a crowd, LED Sign is built so any moment can be turned into light, in under 10 seconds.
