Reply To: Why do LED running lights turn off while the turn signal is blinking?

There are federal standards on vehicle lighting so it is probable that the extra bright LED would cause the non LED turn signal light to fail to meet the standard.
Many current year models also use an LED for turn signal – my Cadillac CT6 has LED turn signals.
So- manufacturers just needed more time to transition to a complete LED lighting system.
