Here is a Whelen V-POD from 3DWarehouse that i had converted to GTAIV by ObsidianGames before i converted it to use on my vehicles on GTA V.
I'm not doing an awful lot of modding at the moment and so have decided to release it so the community can make use of it! Its not perfect and there are texture issues (where i haven't textured properly!) however it looks the part!
