I have a 2024 Fleetwood Discovery LXE 40M.  There are white marker lights just aft of the rear axle, one light on each side. These lights are on 24-7.  We are parked at a RV  park and connected to 50A shore power.  The lights do not turn off with any of the outdoor lighting or undercoach switches.  None of the vehicle chassis running lights are on.  I figure if these lights were meant to be side marker lights, they would be amber colored, but they are white.  

Any ideas what these lights are for?  

Thanks
