We had the same problem with our lights.....you could literally count seven seconds in between the pulse of light. We had the XLR service manager and plant manager in Goshen, take a look, and same thing....they couldn't see the lights pulse. They tested our battery, and it was fine, but they put in a new one....just to be sure. Well, lights kept pulsing again....next day they came and checked the converter...sure enough.....that was the problem! That was replaced...and the lights work perfectly now!
Thank you FR!!!
