Metal Pushbutton with LED Ring and RPi

I am looking at using two or three of the Waterproof Metal Pushbutton with Blue LED Ring (https://www.adafruit.com/products/481) in a project with my Raspberry Pi. Can the Pi GIO drive the led in this button ok? What value of limiting resistor should I use?

You can drive it as you would a typical 5mm blue led. Somewhere in the 220 ohm range should work.
