The Game Boy Light, released exclusively in Japan on April 14, 1998, retained all of the Pocket's improvements, including a more compact design and clearer FSTN LCD screen, while introducing several enhancements of its own. The most notable addition was an electroluminescent backlight, enabling gameplay in low-light conditions for the first time without external accessories. The backlight emitted a blue-green glow, similar to the illumination used in digital wristwatches at the time. To address the criticism of the Pocket's battery life, the Game Boy Light used two AA batteries with greater capacity, offering approximately 12 hours of gameplay with the backlight on and up to 20 hours with it off. These upgrades resulted in a slightly larger and heavier form factor compared to the Game Boy Pocket, though it remained significantly smaller and lighter than the original Game Boy. The Game Boy Light was available in gold and silver color variants and launched at a retail price of ¥6,800 (equivalent to ¥7,502 in 2024).
