First, if you post please use the # button to tag code correctly

Give this a try, I removed a { and added an extra delay(200) , .. (code not tested)

const int buttonPin = 2; 
const int hl = 3;
int buttonState = 0;

void setup()
{
  pinMode(hl, OUTPUT); 
  pinMode(buttonPin, INPUT); 
}

void loop()
{
  buttonState = digitalRead(buttonPin);
  if (buttonState == HIGH)
  { 
    digitalWrite(hl, LOW);
  } 
  else 
  {
    digitalWrite(hl, HIGH); 
  }
  delay(200);  // extra

  digitalWrite(hl, HIGH);
  delay(1000);

  digitalWrite(hl, LOW);
  delay(1000);
}
