According to the United States Census Bureau, there are 19.3 million military veterans as of 2014 — many struggling to transition back to civilian life after having fought overseas, suffering from post-traumatic stress disorder (PTSD) or physical injuries. While some people have expressed their gratitude to these brave men and women directly, others are unsure of how to extend their thanks.
The Greenlight A Vet initiative, which is sponsored by Wal-Mart, provides a simple answer. By switching a single visible light in your home (such as your porch light or in a street-facing window) to a green bulb, you show your support and appreciation for their service. The color green was specifically chosen for its positive associations with health and prosperity; the Greenlight A Vet website notes, “ ‘Greenlight’ is also a term commonly used to activate forward movement. The simple action of changing one light to green is intended to spark a national conversation regarding the recognition of veterans, and ‘greenlight’ them forward as valued members of our communities.”
