First off, I have absolutely no clue what I am doing. All I know is how to solder, that electronics need a power supply and that usually wires need to be connected.
Now, what I want to do is to transmit a wireless signal from one car to another, namely that a blinker has been activated, so that it would be able to warn a car 2 or even 3 cars back.
Thanks so much!
Please ask questions because I'm sure you need more info than that and also please help because I'm excited about this.
can you please explain a bit more in details what you want from the project. I am sure you know more than you said, but if that true, then you are thinking too far ahead.

Nice safety idea but....
What you want can probably only be done with radio.
Radio transmitters are difficult to make directional, so the signal would propagate in all directions and be picked up by every car nearby, even those going in the opposite direction. Not too bad on a fairly quiet stretch of road, but imagine the effect in the midst of a traffic jam in a two-way street with everyone wanting to turn one way or another. I'd turn the damn thing off before attempting to drive in London.
And how many drivers don't bother to use their indicators when turning? In one place I know, it's as high as 80%.

Light is a wireless signal; IR light is also not visible and easily directional.
How I would approach...
IR LED of high-intensity variety mounted in rear window with flashlight-ish reflector. Sends out signals pulse with: sync header + L/R data + repeat count + checksum. Initial repeat count = 0.
1st car behind turning car picks up signal front IR receiver and repeats it out back window BUT adding +1 to repeat count.
2nd car repeats #1 car ...
After "n" cars, the repeat does not happen... Based on some magic number... City vs rural, speed, etc.
Cars that receive the signal perform whatever notification is intended... Sounder, beep, LED, etc.
