LED Lighting for Trailers

High-count marker and rear lighting for long combinations

Where the Problem Starts

A semi-trailer can carry dozens of lamps, so unit cost, current draw and seal reliability all multiply. This is where the 4 inch round and 6 inch oval families and the 0.75 inch markers do most of their work.

Pain Points

  • Marker strings overloading circuits when each lamp draws too much
  • Spliced lead joints corroding and taking the string down
  • Vibration cracking rigidly mounted lamps on rough ground

What Buyers Ask For

  • Low-draw three-diode markers for long strings
  • Sealed connector rear lamps
  • Grommet mounting to isolate lamps from the frame
