Wireless LED Answered

where can i get a transmitter for a wireless transmitter like this : http://www.zenreich.com/ZenWeb/motorcycle/riderlight.htm

and how do i build something like that ?
i need one for my brothers small battery powered scooter. i have most of it ready except for the transmitter, and i don't know what to do to make the LED's have a receiver.
help !


go to sparkfun.com and search for RF link. It's pretty cheezy stuff, but it's $10 for a system.
