Default What is free CH1 in stock TRX4 receiver for? Tried to install cheap LED lights

Hello.
I tried to connect simple LED lights, I once found on archieved forum post that it can be done stricte from receiver; so I did.
LEDs went alive but my servo (stock) turned maximum left and I still dont know why? I disconnected everything rapidly. After turning TRX4 back to live, servo worked correctly.
I think I will buy some 12V leds and connect them to the ESC JST....?
I'm afraid on burning anything down :(

edit:
it's TRX4 Defender

Traxxas has 2 number 1 slots so both are for steering as some Traxxas rigs have dual steering servo.

so its
Steering Channel 1 slot 1
Steering channel 1 slot 2
Throttle/ESC Channel 2
Then chnl 3, 4, 5.

So use slot 3 or 4 or 5 for the lights.
