How can I enable vibration and lights using the Android notifications api ?

Question

I have created an application that creates notifications, using the following code:

// notification
Notification notification = new Notification(R.drawable.notification_icon, title, System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;

// parameters
String ringtone = prefs.getString(context.getString(R.string.key_notifications_ringtone), "");
if (ringtone.length() > 0) {
    notification.sound = Uri.parse(ringtone);
    notification.audioStreamType = AudioManager.STREAM_NOTIFICATION;
}

boolean useVibrator = prefs.getBoolean(context.getString(R.string.key_notifications_use_vibrator), false);
if (useVibrator) {
    notification.defaults |= Notification.DEFAULT_VIBRATE;
}

boolean useLed = prefs.getBoolean(context.getString(R.string.key_notifications_use_led), false);
if (useLed) {
    notification.defaults |= Notification.DEFAULT_LIGHTS;
    notification.flags |= Notification.FLAG_SHOW_LIGHTS;
}

// alert
RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.notification);
contentView.setImageViewResource(R.id.notification_icon, R.drawable.icon);
contentView.setTextViewText(R.id.notification_title, title);
contentView.setTextViewText(R.id.notification_text, text);
notification.contentView = contentView;

Intent notificationIntent = new Intent(context, MyActivity.class);

PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.contentIntent = contentIntent;

notificationManager.notify(1, notification);

The notification works, and the correct ringtone is used.

However, even though the preferences are correctly activated and notification flags are correctly set (I checked by debugging), the notification never vibrates and never cause the lights to be activated.

I would have blamed my phone's settings, but every other app using notifications, like messaging, gmail, and others correctly use all these features.

May someone know what I did wrong ? (my phone is a HTC Hero with Android 2.1)

Add permission to your manifest file

<uses-permission android:name="android.permission.VIBRATE"></uses-permission>

EDIT

For Lights try adding them explicitly, the Default light might be configured to be nolight

notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notification.ledARGB = 0xff00ff00;
notification.ledOnMS = 300;
notification.ledOffMS = 1000;
