I think it was only like 24 hours. It’s all automated though. So you get a thirty second countdown mashing buttons to try and work out how to get your headlights on if you spawn at night.
I actually made it because I got banned because I couldn’t use my lights in euro truck simulator 2 multiplayer mod. I’m not sure I’d want to use it in any competitive games as it’d likely break off if I got mad.
It’s an extra 12 button Bluetooth controller using an esp32 dev board. So your games need to allow you to use multiple controllers. You could also program it to send keyboard keys but I haven’t tried it.
You can download an stl for the battery cover. I modified it to allow the backpack controller to attach to/detach from the main controller. The original is in a box somewhere safe and well.
