Yes, but it's not recommended because not all HID components by various manufacturers fit each other. You have to know what works with what before you create your own kit. 

There are two different approaches:
1. Plug and play HID kits - a very simple install of hooking up the kit per the instructions usually with no cutting or splicing of wires.
2. Projector retro-fit - a more difficullt and expensive install since you have to cut open your headlights to install projectors. This is the proper way to install HIDs for the best light output.

If you want to create your own custom kit like GoonzSVT, do the research to understand what it takes.
