I spoke to a Furrion engineer about this. They gave me a link which explains this. I also found out from GMC they began putting Lamp Out Sensors in their vehicles in 2015. Furrion also states they have this issue in Ford and Ram vehicles as well. I see this issue at higher speeds. I have never had it happen when backing up. For $16.95 I am going to order one and try it out.
