The wig wag lights at the hold line for the runways are too [bright] and destroy dark adaptation.  Thus endangering night flight.  This is a Safety of Flight issue and probably exists throughout the system. Tower/Ground Control tells me that they are dimmed as low as they go.Please help because night vision is important to see and avoid in VMC/VFR flight.
GA pilot reported the wig wag lights at DVT airport are too bright and affect night vision adaptation.
