I'd say that it would be called illegal. Unless I'm missing something, the Spark would destroy any LED assembly you could put on it. The maximum current it can supply for 2 seconds is 100A. The LED rings that we, and many other teams, are using use the 12V/500mA port on the VRM. The illegal part here is that doing this would be unsafe. Even if you configured the Spark to not deliver anywhere near that much current, I think that it would still be ruled unsafe.

What you could do is put a resistor in series with the LED ring to abate the current issue.
