Big T Flash Beacon Mod
This the original mod from Big T. This was released for ETS2 version pre 1.15 and still works in ETS2 to 1.22. I tested it with no framedrop or other issues. I have simply updated it for ATS. I have lowered the unlock level from 9 to 1, and price has been reduced from $175 to $50 each.
Original creator is Big T, I just updated it for ATS.
