He used photoshop I bet. And he possibally imported the images into the game. You can find the folders inside the main Garry's Mod directory.

But at the same time I'm not sure you should check it on youtube.

in all honesty all i know is i think they may have essentially just. added an image file of some kind to the list of options available to spotlights, however i am unsure on how exactly this works as i've never made any gmod mods before

pretty simple

1. create your logos make sure they are png
2. convert them to vtf
3. create a folder and name it how you like it to
4. add the following folders in the folder

• lua
  
• materials

(make sure case sensitive)
5. in the lua folder add a new folder called autorun
6. in the autorun folder create a .lua file and name it whatever you like (for later)
7. go back to the root of the folder and go to materials
8. make a folder called effects and in that folder make another one called flashlight
9. move the logo you recently created and converted into vtf in the flashlight folder
10. go back to the root of the folder and then go to lua > autorun > insertnamehere.lua
11. in the lua file add the following line
list.Set( "LampTextures", "vtf location here", { Name = "name here" } )
12. replace the vtf location here with the location where you placed the vtf and the "name here" with any name you would like for example

list.Set( "LampTextures", "list.Set( "LampTextures", "effects/flashlight/mylogo", { Name = "aperture logo" } )", { Name = "my logo" } )

13. save it
14. close out of the folder and move the folder with all of the stuff in it into
C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\addons
15. done
