Game Boy Color Frontlights are here.
Alternatives to the AGS-001 front light mod for the Game Boy Color are few and far between. This light guide panel has micro laser dots that enable decent lighting for an LCD underneath, especially with an liquid optically clear adhesive (LOCA). We will admit, the optics of this mod are not perfect as there are near 7 surfaces where light is reflected and refracted beneath. Using LOCA will help improve the optics and therefore make your front lighting experience more enjoyable.
LOCA is not necessary but highly recommended for the best user experience. Make sure you orient the panel properly BOTH with LOCA and especially without. Red wire should be on the LEFT.
