Go to the market and get this Alarm app, been using it for the longest, it is fantastic, once loaded, set it up and then click on icon once you are ready to go to bed, you can view the phone in horizontal and landscape mode, it shows you the current time, alarm time and battery charge indicator, after a few minutes the screen goes black and only the time shows as to not light up the room. It works the same on any Android phone.
