ListItem pulse lighting

Hello, I need light some ListControl item, how i can do this? its must be pulse animation.
the item creating like

Code (text):

 foreach (var item in contactsList)
            {
                GUIListItem guiListItem = new GUIListItem("Item 1");
                guiListItem.Label = item.GetContactDisplayName();
                guiListItem.IconImage = SkypeHelper.Instance.GetImageForContact(item);
                guiListItem.PinImage = BuildMemoryImage(item.GetAvatar(), "itemava");
                facadeOne.Add(guiListItem);
                guiListItem.OnItemSelected += new GUIListItem.ItemSelectedHandler(guiListItem_OnItemSelected);
            }

facadeone is ListControl.
may be i can use PinIcon for show selection? but i can change PinIconWidth and PinIconHeight.
