Modifying Light Sources

[MaXiMiUS]

I'm trying to modify the following light source: PipboyLight640

 

I want to change it's radius from 640 to 2048 (which means changing the byte at offset 155 from 03 [640 radius] to 08 [2048 radius])

 

Here's the Hex for what I have so far:

000000000000803F0000B4420000000000000000464E414D04009A99993F

 

I can't figure out WHY none of my changes to this light source are showing up in-game.

 

Even if I set the light radius to FF [256 + (256*256) = 65792] or 0F [(256*256) = 65536], still -nothing- shows up in-game.

 

Maybe I should try hex-editing Fallout3.esm itself and see if the changes take effect? >_<

 

I'm -certain- I've figured out where the radius and color data is stored in light sources in Fallout 3.. Bah.
