Making Commercial Vehicles Impossible to Miss: A Proactive Approach to Trailer Visibility & Safety
Published by RoadLites. Announced April 2026.
In low-light and poor-visibility conditions, trailers can become difficult to see. The white paper examines why lighting that meets minimum requirements does not, on its own, solve that problem, and sets out the case for continuous contour outline visibility — lighting that defines a trailer's full shape, length and position and stays visible at all times rather than only during braking.
What's Inside the White Paper
- The gap in current trailer lighting standards
- Why visibility — not just compliance — matters
- How outline marker lighting improves safety outcomes
- Real-world applications for fleets and drivers
