I used some Puck style surface LED lights from "Hella" they were like $28 each. You can do it much cheeper. Mike did some LED cup holder's in his SV211 that had only one signle LED sitcking up threw them. I have not seen them at night so I dont know how bright they are gonna be. "But I will not be out Blinged in the LED cup holder depertment by mikes single LED" LOL Im guessing if you used the LED cluster's that wakespecialty uses your gonna have to do quite a bit of work because it would be like adding a rock to the bottom of your cup holder and now your drink is gonna have a pimp limp. Thats the reson I went the route I did it was a drop in application.
