Working flashlights on weapons

On the official forum, Master_Chief has posted some screenshots of a working flashlight on weapons.

There are several advantages:

-no scripting required.
-AI soldiers use it during combat without using scripts.
-player uses it like the lights on a vehicle, by pressing “L”.
-simple for AI to turn on, off by default.
-some insane night MP games with no nvgoggles.

There are however some major disadvantages as well:

-doesn’t line up with individual guns.
-there is a slight problem when moving the gun vertically, if the gun doesn’t move fast enough the light will sometimes not move, but it isn’t really that noticable.
-This is all done using OFP’s rather bad lighting system, so small things like rocks and trees look great but bigger things don’t work as well.
-the light doesn’t illuminate the ground except on higher terrain detail settings.
-cant be added onto existing soldiers without modifing their models.

He has also made a video.

Note: units shown are from Halo mod.
