Lighting and MarkingAEM member experts have developed an illustrative guide to provide an easy-to-understand visual guidance for the application of the Lighting and Marking Standard for Agricultural Equipment, ASABE S279.17.

This visual representation is intended to help stakeholders understand and navigate this standard that can be difficult to interpret, particularly for those who do not routinely read and apply standards or participate in the standards development process. Target audiences span all potential stakeholders, including manufacturers, law enforcement and equipment owners. The graphic representation of the standard helps to provide a common understanding given the old adage that “a picture is worth a thousand words.”

This 12-page document provides graphic representation of the front and rear views of multiple equipment forms, including agricultural tractors, agricultural sprayers, harvesters and mounted and towed equipment. Separate views illustrate equipment wider than 12 feet and similar views for equipment narrower than 12 feet.

To promote this work across the industry, the following steps are planned:

  • AEM will host a webinar to promote this work to all stakeholders.
  • Presented by an industry expert, the webinar is planned for later this year, pending speaker availability (to be announced later).
  • Promotions will be extended to Law Enforcement, AG Extensions, Ag Safety NGOs and Ag Equipment Association members.
  • The free webinar will be recorded and archived at
  • The Illustrative Guide will be available after the webinar through the AEM Materials Store.
  • The guide will be proposed for inclusion as part of the formal ASABE standard, which could be re-numbered S279.18. This work will commence mid-year.

The guide provides a common interpretation of the lighting and marking standard for manufacturers, law enforcement and owner/operators. It will eliminate confusion due to different interpretations of the standard, and will contribute to readily recognized agricultural equipment being operated among traffic, enhancing roadway safety.
