They are available from bike mp3, are they a sponsor? if not do other vendors sell them?
They now are offered without a switch...while i'm a more is better guy, I also try to "keep it simple stupid" Can you think of a good reason to buy a switch (35$ upcharge) ? I really intend to use them as DRL's and I dont ride at night much, if at all so they would be on all the time..
Are they truly plug and play? ie no splicing?

Anything else I should be aware of? (they are a lot of money)
