Over the past decade, blue porch lights have grown in popularity. A 2022 survey by Porch Trends found that 12% of American households displayed blue porch lights at some point, up from just 5% in 2015. Social movements, awareness campaigns, and viral online trends have fueled this growth. While blue lights once primarily signaled support for law enforcement, their meanings have diversified.

Why We Notice Blue Lights Most During the Holidays
The holiday season naturally draws attention to home decorations. The contrast of a stark blue light against traditional reds and greens makes it more noticeable. Many homeowners also use this time to express support for causes important to them, turning a simple light into a symbol of solidarity.

Support for Law Enforcement
One of the most common meanings of a blue porch light is honoring law enforcement officers. Initiatives like the ‘Project Blue Light’ campaign, started by C.O.P.S. in the late 1980s, encourage displaying blue lights to remember fallen officers and show community support. Today, many households continue the tradition as a gesture of appreciation.

Blue Lights and Autism Awareness
Blue lights also symbolize autism awareness. The international ‘Light It Up Blue’ campaign by Autism Speaks encourages households to show support for individuals and families affected by autism. While April is Autism Awareness Month, many people display blue lights year-round as a sign of inclusivity and understanding.
