AFAIK, there’s only one port of ELS for FiveM made by @ejb1123, located at
[ALPHA] ELS FiveM v0.0.4.0 [FiveM-Scripts]
Now, it doesn’t have the lights. Nor do I think it will for a while (if ever). This is because the original developer apparently doesn’t like open source projects and has decided to keep his code to himself (the same as like 90% of people who release GTA mods). So, until they decide to let people see the code, they port it over themselves, or give the patterns (heard somewhere that the patterns are the hardest bit) you won’t see a fully working ELS script (fully synchronized with all clients).
Lol what? If you don’t infringe on others copyright and steal their scripts (like every other community), it’s a great place. It’s not our fault if mod creators
are complete twats don’t want to give other’s the source code to their precious mods.
