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.
