Turn Backlight off of LCD

I was wondering if you can turn off the LCD backlight of a LCD1602. If so what would the code be for it? Im using the LiquidCrystal Library by Adafruit v. 1.0.7

it depends on your wiring. But in the end it will be a simple

digitalWrite(lcdLedPin, HIGH);

or

digitalWrite(lcdLedPin, LOW);

Do a find in the source of the library: first LCD library I looked in had functions backlight()and noBacklight().
