Your ex-husband changing the porch light to green—especially in connection to his father’s recent passing—was likely his quiet way of honoring or remembering someone important to him, even if he didn’t explain it in detail.
1. Support for Military Veterans
The most well-known meaning comes from the “Greenlight A Vet” campaign, launched in 2013. The green light shows appreciation for veterans transitioning back into civilian life. If your ex-husband’s father served in the military, this might be his personal tribute.
2. Mental Health Awareness
Green also symbolizes mental health, healing, and balance. He may be using it to bring awareness to emotional well-being—either in remembrance of struggles his father faced or as a symbol of support.
