Backlight:

To activate the backlight on module 5416 powered G-Shocks, press the bottom right button.

The 5416 has a modern EL backlight (aka Electroluminescent Lamp) which provides a brighter light covering the entire screen. Although an EL backlight requires less power than a traditional LCD backlight, Casio states that the battery claim of approximately 7 years only includes using the backlight for 2 seconds per day. In other words, using the backlight too many times and holding the button too long will drain your battery significantly.

Interesting note from Casio:

“The watch will emit an audible sound whenever the display is illuminated. This is caused by a transistor that vibrates when the EL panel lights up. It does not indicate malfunction of the watch.” -Operation Guide 5416
