My experience with LED lamps for motorcycle use is that the driver generates RF interference that wipes out fringe FM reception on the motorcycle. Down here in Ocean County, pretty much everything but WOBM is fringe :-( LED drivers are high frequency switchers so they are all going to generate some RF. I would be tempted to ASK the radio guys if they can recommend LED lights that have low emissions. They are the experts, and it's "their problem" if our lights piss all over their radios. ALSO: My brother works for an LED lamp manufacturer. He says that the consumer grade Cree lamps are inexpensive because Cree has chosen to overdrive the LEDs, counting on the unlikeliness that people will take a 4 year old burned out LED light back to the store (or mail it back to Cree). In other words, Cree is gambling their good name to chase short term profits. Bill Dudley This email is free of malware because I run Linux.
