    The article claims:

    “Until the last decade, LEDs could only produce green, red, and yellow light, which limited their use. Then came blue LEDs, which have since been altered to emit white light with a light-blue hue.”

    . . . then how is it that my old 1987 VW Jetta had a blue LED for its high-beam indicator?

    BSNBC reporting at its best, whatever that’s worth. . . .
