Retextures the laser pointers in "Weapon Mod Kits" to a much higher quality and a variety of colours. I created my own HD texture and graininess.

Requires Weapon Mod Kits: http://www.nexusmods.com/fallout3/mods/3388

Colours included:
> Red
> Pink
> Purple
> Blue
> Cyan
> Green
> Yellow

Once activated in NMM, if you wish to change it from the default colour (blue) navigate to: "%FALLOUT3DIRECTORY%/Data/Textures/weapons/WMKweapons/common" and rename "laserpointer01.dds" to the colour it is and then the one you want to "laserpointer01.dds".
