Blue lights in front of electric poles serve as visual indicators to alert and guide emergency personnel such as law enforcement, firefighters, or other first responders. These lights are commonly referred to as "emergency lights" or "emergency beacons."
The purpose of these blue lights is to provide a visible reference point for emergency personnel in the vicinity. By having these lights installed on electric poles, it becomes easier for emergency responders to locate an incident or a specific address quickly, especially in areas with limited visibility or during nighttime emergencies.
In some regions, blue lights may also indicate the presence of a designated emergency vehicle parking spot or serve as a marker for emergency services access points.
It's important to note that the specific use and regulations surrounding blue lights may vary between different jurisdictions or countries, so local guidelines and laws should always be followed.
