What is the purpose of the buddy lights on the SCBA?

The buddy lights on the SCBA serve to provide a visual alert for alarms. These lights are an essential safety feature that enhances communication and situational awareness among team members in high-stress environments, such as during firefighting or rescue operations. When an alarm is triggered, such as for low air supply or in the event of a malfunction, the buddy lights become illuminated, allowing nearby personnel to quickly identify that a team member may be in danger or in need of assistance. This visual signaling helps ensure the safety of the wearer and the entire team by promoting prompt response in critical situations.
