2 LED flasher with one pushbutton

Projects Programming
1

I'm new in arduino. Trying to build custom motorcycle lights control.

Basicly i need one push button to do 3 functions.

1 click turn on LED1 blinking till press one more time
2 clicks turn on LED2 blinking till press one more time
3 long press turn on LED1 and LED2 to blink till next long press.

const byte buttonPin = 7;
const byte ledPin = 13;
boolean flashing = false;
byte currentButtonState = HIGH;
byte previousButtonState = HIGH;
unsigned long currentTime;
unsigned long onoffStarted;
long flashPeriod = 1000;

void setup()
{
  pinMode(buttonPin, INPUT_PULLUP);
  pinMode(ledPin, OUTPUT);
}

void loop()
{
  currentButtonState = digitalRead(buttonPin);
  if (currentButtonState != previousButtonState && currentButtonState == LOW)  //button has become pressed
  {
    flashing = !flashing;
  }
  previousButtonState = currentButtonState;          //save the button state for the next check

  if (flashing)
  {
    currentTime = millis();
    if (currentTime - onoffStarted > flashPeriod)  //if the flash period ended ?
    {
      digitalWrite(ledPin, !digitalRead(ledPin));  //flip the state of the LED
      onoffStarted = currentTime;                  //save the time when it occured
    }
  }
  else
  {
    digitalWrite(ledPin, HIGH);  //force the LED off if not flashing
  }
}

I trying to understand from basics.. so trying to play first with one function, and its working fine. how i can set second function to button for turning on second LED?
