OneWire or TwoWire LED chaser design

I need to design a LED chaser that will be powered by a 12V battery. It needs to have a master PCB which will control all the slaves connected. The slaves will be chained together and distanced about 5 meters apart with a 4-pin connector IN and 4-pin connector OUT. Each slave will have a 12V lamp attached and switched by a mosfet.

The requirement is to make a plan on what microcontroller, ic's and other parts to use, and which technologies to use to achieve this. Create a prototype on ready made hardware like an Arduino or similar. And develop the code which will run this.

Preferably something cheap and accessible and easy to use like this:

[url removed, login to view]

But if the Arduino hardware and toolchain cannot achieve this then anything is acceptable.

The PCB layout and design ill make myself once the plan is prototyped. You will develop the code.

A big note to look out for is that OneWire or TwoWire is a must, there cant be more then 4 wires. Also the slaves (slave1, slave2, slave3, slaveN) can be connected in any order (so no marking's on the slaves that this is number 1 connect it to the master, this is number 2 connect it after slave1 etc.)

The lamps connected to the slaves are also fixed, so no addressable LEDs or anything similar.
Look at the attached picture.

At first look I would recommend running an I2C bus (2 wires) through the setup. It can run very long and you only have to use one microcontroller, the rest would be cheap ICs so it will end up very cheap. However, t Flere
