Jerry, what color do you want? I'll check my spares drawer.
Otherwise:
www.oznium.com,
www.besthongkong.com, or superbright are all good options.
Just wrap your existing cupholder with LED tape and raise it up with a clear 3/8" plex ring. Machine cut the plex ring, laser cut will leave it clear where you can see the LEDs. I had to sand the laser rings TAP cut for me.
