A partial fix is available (as mentioned in the first post)
open your aircraft.cfg find your VC light and swap the trigger from (for example) 4=cockpit to 2=strobe
[LIGHTS] // types: 1=beacon, 2=strobe, 3=navigation, 4=cockpit, 5=landing light.0 = 3, -0.6, -23.495, 1.796, fx_navred , light.1 = 3, -0.5, 23.495, 1.696, fx_navgre , light.2 = 4, 0.70, 0.00, 2.050, fx_vclight, // instrument panel light.3 = 2, -4.70, 0.00, 3.250, fx_vclight, // cabin light
example above would then make the strobe switch your cabin light switch
Only a workaround, but you can adjust the aircraft.cfg in-game, and re-select your plane from the menu to see any changes
I can live without the strobe, but I can fly better without the interior light constantly on
