The electronic candles advertised at C. Crane claim to flicker sometimes
as if an occasional breeze had blown them.
I would suggest using an orange and yellow LED, driven by 2 different
generators, for a warm color and lively feel.  Stay away from incandescent
lights and filtering/baffling unless battery life is of no consequence -
moderate
brightness at moderate current is your primary goal.
