Posting for those experiencing "converter burnout."
I wired my trailer with LED lights so I wouldn't have to track down and replace my flasher with a heavy duty one. Since then I have burned out 2 tail light converters. After a while the brake lights quit working, and it kills the TV lights, too.
I contacted Hoppy last night and they told me the converter I was using is not intended for use with LEDs. They are sending me a new "LED compatible" converter - no charge, no questions. You might say that's the right thing to do, and it is, but I have dealt with plenty of companies that would try to get by with less.
It's nice to run into a company where integrity matters.
