Inner Edge / Traffic Advisor
A rear Inner Edge can make a great rear warning option on discrete vehicles. If using a Whelen CenCom or CanTrol system consider using a Traffic Advisor with your choice of colored lightheads for the most configurability.
License Plate Lights
For more centralized lower zone warning consider adding IONs or M4 lightheads to the license plate area.
