can someone double check my code?

i just ran this:

void setup() {
  // initialize the pins outputs:
  pinMode(redPin, OUTPUT);
  pinMode(greenPin, OUTPUT);
  pinMode(whitePin, OUTPUT);
  pinMode(sirenPin, OUTPUT);
  pinMode(brightPin, OUTPUT);
  
  // initialize the pins inputs:
  pinMode(redButton, INPUT);
  pinMode(greenButton, INPUT);
  pinMode(startSensor, INPUT);
  
  
}
void loop(){
  
  digitalWrite(redPin, HIGH);
  delay(1000);
  digitalWrite(redPin, LOW);
  digitalWrite(greenPin, HIGH);
  delay(1000);
  digitalWrite(greenPin, LOW);
  digitalWrite(whitePin, HIGH);
  delay(1000);
  digitalWrite(whitePin, LOW);
  
}

and all the led's checked out with the hardware so i ran my edited code with the "else &&, and ||" with simplified hardware(not installed onboard leds), and that checked out.
so ill test it with the more complicated set of hardware(installed in skull, external led's) but i expect it to work.
i dont get how the && could change that its in an entirely different part of the code but that may hove been the problem?
