1. Cut the power/unplug
2. Loose 2 screws and take out the lamp holder.
3. There are 2 cables connected to the holder. Unclip them (Don't worry, they're in a different size. You can not attach them to wrong connectors)
4. Clip the cables to the holder (One is slightly smaller and fits a slightly smaller connector)
5. Push back the holder to original place and screw (You'll use existing screws. No replacement in the box)
6. Turn on the power/plug-in
7. Let there be light!
