The Office of Investigation and Analysis released Marine Safety Alert 13-18 to alert mariners about reports regarding poor reception on VHF frequencies used for radiotelephone, digital selective calling (DSC) and automatic identification systems (AIS) when in the vicinity of light emitting diode (LED) on-board ships (e.g., navigation lights, searchlights and floodlights, interior and exterior lights, adornment). Radio frequency interference caused by these LED lamps was found to create potential safety hazards.
