Help with MuzzleFlash Script

So I have this script from UltimateFPS Camera package for the Muzzleflash. Is there any way to add to the script a few lines to make the muzzleflash actualy bright the area around up (with a light of course) when I shoot? Here's the script: ///////////////////////////////////////////////////////////////////////////////// // // vp_MuzzleFlash.cs // © VisionPunk.
