I purchased a strobe system here off of Team Kitfox a couple of years ago. I had to replace one of the light elements but, it was working fine when I took my plane to the airport. About a month into my flight testing, they quit working. I've looked at the elements but they look fine and unless they both blew out at the same time I don't think it's these. I checked my fuse and it is okay. So, I'm wondering if the power supply is failed. Does anyone know how I could assess this?
