Ok so for my project Im trying to wireless connect an LED with another LED. I have attached how my project looks like.
My project is a reminder box serves to remind users if for example their lights are left turned on before they leave the house. The switches on the right side is to simulate a room whereby if i switch it on, the Led to its left acts as a room light and one of the LEDs on the far left will be turned on. This shows that one of the room lights it left on.
I want connect the Room LED( the centre column) and the far left column LED wirelessly so that if the room LED is turned on, it will automatically turn on the reminder LED on the far left column. I have a 4 channel remote control ( attached file ). Is it possible to do it with this remote control transmitter and receiver ? if not what other cheap ways can i execute this project?

If you tape the transmitter in place, next to 4 servos, and you rotate a servo to press a button, then yes.
Otherwise, no.
if not what other cheap ways can i execute this project?
Just remove the light bulb when an offender leaves it on.
In order to comment on other RF solutions, one would need to know the volume of data to be sent, the distance (and what kind of obstructions exist), and how critical it is that the data get through.
Simple 433 MHz transmitter + promini at each room, with light sensor feeding promini on/off data. Promini sends out light data at some sample time (say once a second).
Simple 433 MHz receiver + promini at central location that listens for transmissions and turns on/off status LEDs as sent.
May get some squashed messages from dual transmissions on occasion. Can change the sample time from the sending units to minimize that, like 5/8 second, 6/8 second, 7/8 second, 1 second or similar. Experiment and see what works well.
If you need longer range, different RF options can be investigated.
