Light modification in aircraft.cfg file???

I was wondering if anyone knows how to modify the position of lights as defined in the "LIGHTS" section of the aircraft.cfg file? I d/l the wonderful Beech Super 18 yesterday and noticed the landing light beams are about a foot below the leading edge of the wing when turned on. I'd like to adjust them so they're properly positioned.Also, does anyone know how to modify an aircraft's texture files to remove it's multi-texturing? Same aircraft has multi-textures, but they're constantly going out of focus. I'd like to convert them to a plain old texture and can live with any performance hit it might cause.Thanks in advance,Dave
