Emergency Brake Light (EBL) aims to avoid (fatal) rear end collisions, which can occur if a vehicle ahead suddenly brakes, especially in dense driving situations or in situations with decreased visibility. The driver is warned before s/he is able to realize that the vehicle ahead is braking hard, especially if s/he does not see the vehicle directly (vehicles in between).

This service architecture is largely based on the ARC-IT service package V2V Basic Safety, with customizations to support local user needs.
