Key Benefits

Who It Is For

Fleets and builders upgrading side marker behaviour on panels already drilled for a standard marker.

Problems It Solves

  • Fixed-output markers cannot serve both marker and warning duty

Application Scenarios

  • Sequential side marker strings on long trailers
  • Service vehicles needing a flashing side warning
  • Upgrading fixed markers without re-drilling the panel
