I tried this and it seem to help for the runway lights.
RUNWAY_LIGHTS_SURFACE_SCALAR=1.8 //scales edge,center,end,touchdown,runways
RUNWAY_LIGHTS_VASI_SCALAR=1.8 //scales VASI lights
RUNWAY_LIGHTS_APPROACH_SCALAR=1.8 //scales approach light bars
RUNWAY_LIGHTS_STROBE_SCALAR=1.8 //scales RAILs and ODALs
I inserted under the [Display] column in FSX cfg
The higher the value the larger the lights.
Now on to the Taxi lights
