Title:Emergency Warning Device and Emergency Warning Device Protective Container
Issuing Committee:Heavy Duty Lighting Standards Committee
Scope:This SAE Standard provides test procedures and performance requirements for emergency warning devices (triangular shape), without self-contained energy sources, that are designed to be carried in motor vehicles and used to warn approaching traffic of the presence of a stopped vehicle, except for devices designed to be permanently affixed to the vehicle, and provides test procedures and performance requirements for protective containers for such emergency warning devices.Note: This document has been reaffirmed February 2006. The date of JAN2000 has not been removed. Thus, it will not affect the expected action from NHTSA for J774 to be rolled into the next FMVSS125.
