Hi, do you use the DX10 preview in FSX? With DX10 preview on, i have problems with lights and textures too and so i dont use it.

Here is my 3d redux lights config:

; X, Z, Y
light.1 =  6,  3.0, -8.10, -15.50,  cs130_taxi //right
light.2 =  6,  3.0, 8.10, -15.50,  cs130_taxi //left

light.3 =  7,   6.00, 18.7,  -7.4, cs130_landing //right1
light.4 =  7,  9.00, 23.90,  -4.00, cs130_landing //right2

light.5 =  5,   6.00, -18.4,  -7.4, cs130_landing //left1
light.6 =  5,  9.00, -23.90,  -4.00, cs130_landing //left2

light.7 =  8,  9,  14.50,  -2.50, cs130_edge2 //right

// light.22 = 4,  41.50,  0.50, -5.50, cs130_vcrd

I dont replace the original lights, i only add some 3d redux lights.

The red cabin light (that is my favorite) dont worked after installation. So i added some lights for this (see above) and i modified the effect file c130_vcrd.fx: Color End=240, 10, 10, 0 (original 140, 90, 90, 0).
So my Cockpit shimmers red...
