Adding MuzzleLight?

[Opticalsnare 12]

Hmm well i been working on this mod of mine and been working on the muzzleflashes which ive added but the thing is i wanted to add a light to some vehicles like BMP3 30mm Cannon, ive got the muzzleflash bit all setup ok but i want to add a light so it lights up the surrounding area a bit but nothing seems to work. Ive tried adding these to the weapons cfg

class 2A72 : CannonCore {
	fireLightDuration = 0.01;
	fireLightIntensity = 0.05;
};

or

class 2A72 : CannonCore {
	flash = "gunfire";
	flashSize = 5;

neither of these work but they work on the weapon PKT or COAX machine gun.... Any advice would be helpful. Thanks :)

Still havnt been able to do this, is there a way to add a light via drop particle effect in a .sqf ?
