Some LED lights are known to generate EMI, which poses dangers when it comes in contact with radio reception. The United States Coast Guard recently published an alert detailing how this interference could affect you and preventing electronic communication between vessels at sea by warning against purchasing certain products that have been found guilty of generating EMI emitters such as harbor cruises boats offshore lighting systems among others.
LED lamps offer boat owners many benefits, including brighter light and long life. For safety reasons though it is important to make sure your LED lights meet the appropriate maritime standards for EMI so they don't distract drivers or interfere with marine electronics on board like GPS systems that may be essential if you plan to take out fishing trips during low visibility conditions when storms are probable.
In order to protect yourself from potential risks associated with radio frequency interference (EMI) while navigating through busy shipping channels both exterior and interior lighting should employ quality models equipped with approved emitting devices.
