This is a pretty standard HID reflector bulb kit. I have the one from DDM Tuning. Essentially you will plug in HID harness to the socket for your existing headlight to power the ballast then the bulb plugs into the ballast. The toughest part of the installation will be determining where you want to mount the ballasts and securely mounting them. I found that part to be a PITA.
But honestly if you are paying $99 for it, that's too much. I would suggest at least giving DDM tuning a look. All this stuff is manufactured in China it's just that some are more expensive than others.. but it really is the same equipment.
And one other suggestion to you is to give some consideration to color. 8K is going to appear very much blue and will produce less usable light than a 5k or 6k would. My personal preference is 5K which will give a tiny hint of blue but is really pure white
And oh yeah.. if you want a high beam, that costs a little extra.
