Hey! Looks like you posted a bad link.. However majority of these installs are just basic drilling and mounting the lights and then wiring them.
LEDglow and eBay both provide pretty cheap LEDs as CarID overcharges to the max.
Remember that these are illegal for street in many states, so the only place you could use them is at home or in a parking lot. In some states they are legal but the only colors disallowed are emergency colors of red and blue as well as strobe patterns for obvious reasons.
Also when going over large bumps especially if you are lowered be sure to go sideways, a friend cracked his a few months ago on his S197, so make sure the are plastic LEDs and not glass neons.
On the other hand I don't really condone or support these, I'm just trying to help you out by providing information, as I know a lot of forum members find these to be "fast and furious rice" and others to find them a decent addition on show cars, so it's your choice how you use them.
If you already have LEDs and are looking for a remote as I wasn't sure how clear you were on your post, try contacting the company who sold them, majority come with a remote or a control box.
Be safe and have fun!
