I have one in my KX1 and it's the best accessory.
I operate all the time from an external 10-cell NiMH pack, and I haven't noticed any difference whatsoever.
You only see very brief flashes while tuning around. When you've got a signal zeroed in it's flashing with the signal, but if you figure conservatively that CW has a 50% duty cycle ( I think it's actually less than that) and the LED draws maybe 10ma, and you are transmitting 50% of the time in a QSO, it works out to not worth worrying about.
On the other hand, the ability to zero beat the other guy.... priceless.
