Side Turn Signal Lamps for Long Vehicles
This SAE Recommended Practice provides test procedures, requirements, and guidelines for side turn signal lamps intended for use on vehicles 12 m or more in overall length, except pole trailers. Side turn signal lamps conforming to the requirements of this document may be used on other large vehicles such as trucks, truck tractors, buses, and other applications where this type of lighting device is desirable. It is not intended for use on shorter vehicles due to the higher intensity requirements of SAE J2039 compared to the SAE J914 devices.
