The set includes everything yo need to light up your RC body. The Controlunit must be connected to the free port at the receiver (also a y-connection cable can be used).
There are different blink sequences that can be set with a included switch. You also can connect it to the steering and speed controller to have flasher and brakelight.
You can add some more LEDs, because there are some free slots in the control unit.
