superbrightleds

I was about to order some of their led's, to complement my soon-to-arrive angel eyes. I already have some of their T13's, which are comprised of 6 leds, but noticed on their site that there is also a 9 led cluster (921's) that seem to fit the same "socket"..

Anyone know if these are suitable for use as running lights? Or should I just stick with the T13's?? Surely the 9 led clusters would be even brighter than (the already impressively bright) T13's...
