Hey Frank, I've called AP about this as I thought it was a defect as well (on a new keypad). The response I received is that the keys are glow in the dark if they're charged a bit beforehand. I haven't noticed this yet (glow in the dark) and am probably leaning towards having to memorize and/or just use my headlight. It is a bit inconvenient and a bit of a design flaw. I find that I really like to have a hand controller and not having one is really inconvenient. Maybe a future upgradable design update will remedy this.
