Heavy-duty trailers
Long, wide and often over 80 inches — the class that needs the identification bar and intermediate side markers.
What this class needs
- Over 80 inches wide, FMVSS 108 adds the three-lamp identification bar at the top of the rear.
- Long bodies need intermediate amber side markers and mid-turn lamps, not just the rear pair.
- Steel light boxes are worth specifying where trailers are backed into loading docks.
Where FMVSS 108 lands here
Requirements change with width and length. Under 80 inches, a combination kit typically covers stop, turn, tail, marker and plate. At 80 inches and wider, the three-lamp identification bar and intermediate side markers come into play — and that is usually where a build runs into trouble.
