Pink porch lights may represent Breast Cancer Awareness Month. Pink porch lights are rare, but chances are if you see one (especially in October), the homeowner is raising awareness of the prevalence of breast cancer. Perhaps they or someone they know is a survivor or passed away from the disease, or maybe they just support the movement. Another simpler reason could be that their favorite color is pink.
- If you're interested in switching to a pink light bulb for breast cancer, October is Breast Cancer Awareness Month and is the best time to make the change.^{[11]
