Notification notification = new Notification(icon, tickerText, when);
… //Do normal notification operations
//Use this if you want to use the default lights for a notification
notification.defaults |= Notification.DEFAULT_LIGHTS;
//Use this if you want custom values for the LED
notification.ledARGB = 0xff0000ff; // Blue flash
notification.ledOnMS = 300; // LED’s on for 300 ms
notification.ledOffMS = 1000; // LEDs off for 1 second
notification.flags |= Notification.FLAG_SHOW_LIGHTS;

{
    NotificationManager nm = 

            ( NotificationManager ) getSystemService( NOTIFICATION_SERVICE );
    Notification notif = new Notification();
    notif.ledARGB = 0xFFff0000;
    notif.flags = Notification.FLAG_SHOW_LIGHTS;
