Well, you COULD have done just a teeney little ultra-simple Google search YOURSELF, and found the manual.
You'd have also found a guide about how to change the bulbs.
But, oh no, its SO much easier to get other people to run around for you.
Would you like to have me come round and show you how to click on this link that it took me all of 60 seconds to find??
