    Why do LED running lights turn off while the turn signal is blinking? Anyone knows?

    I've noticed in several new vehicles the following scenario:

    Vehicle is traveling with LED day-time running lights around/adjacent to the headlights
    Vehicle activates turn signal indicator
    Vehicle shuts off LED running light while turn signal indicator is flashing
    LED running lights turn on once the turn signal indicator stops
    Here are the cars I've seen seen this happen:

    Jeep Grand Cherokee
    Audi Q5
    Kia Sportage
    Ford Focus
    Why don't the LED running lights stay on while the turn signal is on?

    Blame it on the Feds. If the turn indicator is in close proximity to the daytime running light, the DRL is turned off during the turn light is in operation. Big brother believes we can't determine that a turn signal is on while other lights are on. The DRL in LED is so bright, that it drowns out the turn signal, according to the government.
