This is a common misconception.
The LIGHT button doesn't turn the light on and off, it turns the light
function on and off, that's a big difference.
When the light function is ON, the light will come on every time a button is pressed, then after a few seconds it will go off again, until another button is pressed.
So, here's what happens when you need to press the LIGHT button twice....
To start with, the light function is on, then you press the button for the first time, which turns the light function off, then you press it again, which turns on both the light and the light function.
The answer is to use some other button to turn on the light, preferably a button that won't do any major harm. Personally, if I can't feel my way in the dark to a harmless button, I just cover up the IR window and press anything.
