Have you ever driven past a house with a brightly colored porch light? Most likely, the colors were more than a design decision. Instead, the homeowner wanted to signify support or awareness for a specific issue.

Let’s take a closer look at different porch light colors and what each one means. The most common porch lights you’ll see are the following:

  • Red light meaning: support for American Heart Month
  • Blue light means autism awareness and support. Also, law enforcement support.
  • Green light meaning: awareness for military veterans
  • Purple light means domestic violence awareness and prevention
  • Yellow light means a sign of friendliness, warmth, and hospitality in various cultures
  • Pink light means awareness to survivors of breast cancer
  • Orange light meaning: support for domestic violence victims
  • White light meaning: practical light purpose and cultural significance

In most cases, the lights are only popular at specific times of the year.

What Porch Light Colors Mean

Let’s take a deeper dive into when they’re used and how they originated. Each colored-light campaign has a fascinating history worth exploring.

Red Porch Light Meaning

If you see a red porch light, it’s most likely meant to show support for heart health.

February is American Heart Month, created to increase awareness of cardiovascular health. During February, the American Heart Association encourages everyone to wear or display red, such as by wearing red clothing or putting a red bulb in their porch light.

Aside from heart health awareness, a red porch light has a few other potential meanings:

  • Halloween: Many people use a red bulb to create an eerie effect during this spooky time of year
  • Valentine’s Day: A red bulb is also a way to celebrate Valentine’s Day. (Of course, this can get confusing, as February is also American Heart Month.)

Another use of red lights is found in so-called red light districts. These are neighborhoods known for prostitution, adult theaters, and the seedier side of life.

Back in the 1890s, brothels throughout the US would place a red light in the window of their establishment as a secret code indicating what kind of business went on inside.

To be clear, this was a practice used over 100 years ago, and it’s long since stopped. If your neighbor has a red porch light, they’re almost certainly promoting heart health and not operating a house of ill repute.

Blue Porch Light Meaning

Blue porch lights have two potential meanings: autism awareness and law enforcement support.

Autism Awareness

A blue porch light is most commonly used to show support for people with autism. In 2007, the UN Assembly officially declared April 2nd as World Autism Day.

Three years later, the autism advocacy group Autism Speaks attempted to increase awareness of World Autism Day by launching the Light It Up Blue campaign. The color blue is used around the world to represent autism.

The Light It Up Campaign encouraged people to put blue bulbs in any house lights visible to the public, such as porch lights. Although April 2nd is the official day, most people keep their blue lights shining throughout the entire month.  

Law Enforcement Support

Although not as widely known as its use for autism awareness, a blue porch light also signifies support for police officers, sheriffs, and other members of law enforcement.

The program, called Project Blue Light, originated back in 1989 by the Concerns of Police Survivors (COPS). It had twin goals: to show support for law enforcement and to commemorate those who died in the line of duty.

Although the program started several decades before Light It Up Blue, autism awareness has emerged as the default meaning behind blue porch lights. However, if you see a blue porch light during the Christmas holidays, it’s likely meant to show police support.

Green Porch Light Meaning

Green lights also have two potential meanings — support for military vets and raising awareness about muscular dystrophy.

Green porch lights have a few different possible meanings, usually depending on the time of year. The most common use of green lights is to show support for military veterans. It’s part of a program called Greenlight a Vet.

The program is meant to create awareness of the many challenges vets face when returning to civilian life. The use of green porch lights is usually at peak popularity around Veteran’s Day (November 11th).

However, the organizers of the campaign encourage everyone to keep at least one green light visible all year. Green porch lights have a few other potential meanings, too. Head’s up! This gets a little confusing:

  • The Light It Up Green campaign aims to raise awareness of muscular dystrophy. You’ll see this most often in August, which is Muscular Dystrophy Awareness Month.
  • A different Light It Up Green campaign also encourages the use of green porch lights, this time for May’s Lyme Disease Awareness Month.
  • If you see a green light in March, the homeowners might be celebrating Saint Patrick’s Day.

While there are multiple meanings, most green porch lights signify support for vets.

Purple Porch Light Meaning

Purple porch lights raise awareness about domestic violence.

The awareness campaign dates back to 2007. The Domestic Violence Task Force, an advocacy group based in Washington State, created the Purple Light Nights, encouraging the use of purple porch lights to raise awareness of domestic violence, honor the survivors, and mourn the victims.

You’ll most commonly see purple lights during October, which is Domestic Violence Awareness Month. While you can buy purple bulbs, they don’t always create a purple color. Try using blacklights, which can create a deeper, more authentic purple.

Flashing or Blinking Porch Light Meaning

If you see a flashing porch light, someone inside might be signaling for help.

Many people will flick their porch lights on and off rapidly after calling for emergency services. The blinking light is meant to draw the eye of approaching police, fire trucks, or ambulances. It’s especially useful at night when addresses are hard to spot.

What should you do if you see a blinking porch light? If you feel a neighbor might be in danger, try knocking on the door. At the very least, you can alert someone to a malfunctioning porch light.

Yellow Porch Light Meaning

The symbolism of a yellow porch light might vary. Simply put, it depends on the nation you are in. Yellow porch lights are a sign of friendliness in various cultures.

It implies that guests are always welcome in your home. In other countries, it serves as an invitation to a business conversation. In rare cases, it may indicate that it is okay to enter the house because there is no political threat. 

Thus, although its meaning may vary depending on the culture or circumstances, understanding its importance can open up various possibilities.

For example, if a person is looking for overnight accommodations while traveling or is searching for new business partners, knowing this simple sign can be helpful.

Things to Consider

Generally, changing a bulb in your porch light is no big deal, but keep these tips in mind:

  • Let the bulb cool. Light bulbs can grow hot enough to burn human skin, so always let the bulb cool before changing. Some large, hot bulbs can take an hour or more to cool down.
  • Always use the correct wattage. Putting a high-wattage bulb into a fixture not properly rated to handle it creates a dangerous fire risk.
  • Don’t paint the bulb. Only use colored bulbs made by reputable manufacturers. Never try to make colored bulbs yourself with spray paint.
  • Make sure the fixture is watertight and rated for outdoor use. Never put an interior light fixture outside.

As long as you follow these safety basics, you should have no problem changing the color of your porch bulb as often as you wish.
