Checklists now include items to test for LED lighting interference with VHF radios and AIS.
Automatic Identification Systems that are non-compliant with adopted international standards can confuse, degrade or even disrupt other users’ systems. The FCC has issued an enforcement advisory stating the use of non-compliant AIS devices is illegal.
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.
