Jason,

The Blue LEDs required more current than the red LEDs. I am not familiar
with the circuit in the refer LED, but many times there is a current
limiting resistor. By changing this resistor to a lower value, the blue
LED will work. Also, some blue (white, etc) LEDs require a slightly higher
forward voltage, as well.

Note that many blue LED flashlights have two 1.5 V batteries, or one 3
Volt lithium.
