Help with HID new bulb purchase and install for novice

Hey,

Bought a used 2003 Civic EX and the previous owner installed what I assume is a HID kit (i am a novice). I have no knowledge of them and one of the bulbs has gone out. I searched the web to find out they come in different sizes and vary on the brightness. It would be a great help if someone could by looking at the pics I have provided let me know what sizes or light intensity I need ( I would like both bulbs to be the same brightness and only plan on replacing one at this time). I also have no idea how to change the bulb I planned on unplugging the plugs I showed in one picture. Any guidance on that would also be greatly appreciated.

Turns out I could not upload my other pictures. I have another pic with the bulb from a side view if this would be more help let me know and I will change the pics.

you will need to find out what type of bulb it is and get another to match it.

OR, do the right thing and put it back to stock so you dont blind oncoming drivers
