What standard do trailer lights need to comply with in Canada?

Trailer lights in Canada must comply with the Canadian Motor Vehicle Safety Standards (CMVSS). These standards are developed by the federal government and outline the safety requirements for motor vehicles and their components, including lighting. The CMVSS ensures that all vehicles, including trailers, meet specific safety criteria to promote safe operation on the roads.

These regulations cover aspects such as the visibility of lights, the color and placement of lights, and the functionality needed to meet safety standards. Compliance with the CMVSS helps to reduce accidents caused by inadequate or malfunctioning lighting on trailers.

While other standards, such as the National Electrical Code, can govern wiring and electrical installation, they do not specifically address the safety requirements for trailer lights under Canadian regulations. The Transportation Safety Standards may include some vehicle safety aspects but are not as applicable to trailer lighting as the CMVSS. Vehicle Emission Control Standards are primarily related to emissions from the vehicle's engine rather than lighting requirements.
