First appeared on Philips/magnavox players in the late 80's. Like coloring CD's. the light must be a complementary to the laser wavelength. Early CD lasers were IR and it was calculated the green would work best.

Modern players with blue ray capacity employ two lasers One blue light and one IR so you need two Leds. or have to compromise

Simply physics used to make a LED kit for CD units, but they probably discontinued it long ago
