The light isn't really neon and it's on all the time. When you pull out the alarm switch, you allow an arm to fall in front of the lens and block the light. Not a bad idea, really but you did sacrifice the reset signal. Remember the first Aladdin?
7H189 The Aladdin
"Has neon light, at bottom of dial,
that glows when alarm is set. No more fumbling in the dark to make
sure you have set the alarm. Designed in a pyramidal shape with moderne
simplicity--has wide base to prevent tipping. Ivory color plastic
case. Light color hands and numerals contrast against chocolate brown
dial. Modestly priced."
