My friend asked me if I could make a simple radio control device.
The preparations are mechanical switches and RC mini servos.
He wanted to control the 12V LED with this switch.
I simply fixed it to tell you how.
He wanted to control only the LEDs, but I also connected the brake lights to the 2CH to test.
If the servo arm is short, the controller may fire at the same time as it moves to the brake state. It would be nice to connect the control module to the 12V LED.
