To adjust the size/intensity of runway ground lighting, add/adjust these lines to your fs9.cfg's [DISPLAY] section:
RUNWAY_LIGHTS_SURFACE_SCALAR=1.0 //scales edge, center,end,touchdown,runways
RUNWAY_LIGHTS_VASI_SCALAR=1.0 // scales VASI lights)
RUNWAY_LIGHTS_APPROACH_SCALAR=1.0 // scales approach light bars
RUNWAY_LIGHTS_STROBE_SCALAR=1.0 //scales RAILs and ODALs)

FS2004 Nick's LightFix Version
2. Adds an all new xenon landing light effect and addresses the following issues
from version one: 1. Reduces the size of aircraft lights to the proper scale
when the aircraft manufacturer uses the airport lights (halo.bmp) texture for
aircraft lights (many Project Open Sky planes use that method); 2: The aircraft
beacons and strobe lights have been redesigned so every aircraft being rendered
in the sim does not flash the lights at the same time. This greatly enhances the
illusion of each plane running individual lights and makes the simulation more
realistic; 3: Provides two optional flashing tower lights (large and small for
different viewing distance); 4: Reduces and better defines airport lights - some
airports were displaying the lights out of scale (too large) and this is fixed
in this release. Like the original Nick's LightFix, this release will
automatically replace all the Flight Simulator aircraft and airport lights with
more realistic ones along with better distance visuals of slower flashing radio
tower/smoke stack and ground beacons. It also includes replacement lights in
scale for the PMDG 737, 747 and for all Project Open Sky aircraft offered on
their site. It works automatically with Ultimate Traffic and other AI add-ons
which use the default Microsoft aircraft lights. A restore package is included
allowing to you to revert back to default textures and FX files. You do not need
my original Nick's LightFix package to install this one. By Nick Needham.
