Ive been looking around for a this and couldn't find anything on it so here it is.
Open up pak01_dir.vpk with notepad++ and search for ÿÿflashlight001 change it to ÿÿflashlight002 and save.
there is only 1 instance so do not change ÿÿflashlight001_infected.
Then put your custom flashlight in left4dead>materials>effects named flashlight001.vtf
I haven't tryed this on l4d2 seeing as i do not play it much but i guess it will be very similar if not leave a comment and ill look into it.
Attachment is my flashlight i have already edited its just a plain white circle what is all you need unless u want it pretty colors or something
Note: If you post this somewhere else with any of my work please inform me or put a link to this post in it.
