This is the sixth edition of CSA M669, Lighting and marking of agricultural equipment on highways, which is an adoption without modification of the identically titled ANSI/ASAE (American National Standards Institute/American Society of Agricultural Engineers) Standard S279.17 JUL2013. It supersedes the previous edition published in 2011 as CSA M669 (adopted ANSI/ASAE S279.15 SEP2010).
This edition adds provisions for self-levelling lamps along with significant updates to the normative references. The changes also include revising the equation for measuring the spectrophotometric colour values of the fluorescent materials.
It should be noted that this Standard applies to all mobile agricultural equipment, whether self-propelled or towed, moving on public highways and roadways (paved, gravelled, or dirt surface).
This Standard provides specifications for lighting and marking of agricultural equipment whenever such equipment is operating or is traveling on a highway.
