Answer

int lightPin = 0;

int ledPin = 9;

int ledPin2 = 8;

void setup()

{

  pinMode(ledPin, OUTPUT);

  pinMode(ledPin2, OUTPUT);

}

void loop()

{

  int lightLevel = analogRead(lightPin);

  lightLevel = map(lightLevel, 0, 900, 0, 255);

  lightLevel = constrain(lightLevel, 0, 255);

  analogWrite(ledPin, lightLevel);

  analogWrite(ledPin2, lightLevel);

}
