NFPA 1900 Overview Ambulance

NFPA Ambulance Lighting Requirements

The following will provide a quick overview of what you need to ensure your small emergency vehicle’s warning light system complies with NFPA 1900. A small apparatus is defined in NFPA 1900 as a vehicle with a bumper-to-bumper length of less than 25 feet, and has the optical center of all optical warning devices at less than 8 feet

For more information see the NFPA Guidelines.

Warning Zones

Rev 5/20

Each apparatus, less than 25 feet long, is divided into eight (8) warning zones – four upper and four lower.

Modes of Operation

Calling for Right of Way: Apparatus responding to an emergency.
Blocking Right of Way: Apparatus at emergency scene. White light not permitted.

Permissible Colors

All colors must meet the SAE J578 color
specification for White, Red, Blue, and Amber.
The diagram at right shows which colors are
allowed in each zone.
Color Calling for Right of Way Blocking Right of Way
Red Any zone Any zone
Blue Any zone Any zone
Amber Any zone except A Any zone
White Any zone except C Not permitted

Flash Rate and Failure

The minimum flash rate allowed is 75 flashes per minute for any single optical source and 150 flashes per minute from all of the light sources visible at any data point (i.e., at least two warning lights are required in each zone). Failure of a lighting device should not leave a data point without a signal.
