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

[lessonstar]

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?

IDK. I may have seen this but chalked it up to a burnt out light. I will be watching for this now.
I would guess it's a safety option. So, the running light goes out to ensure the pulsing of the blinker is observed. With the advances in automotive lighting and the acceptable range of colors headlights are brighter and more difficult to look at. Same could be said for the blinker. Advanced lights and brighter.
From there it comes to reuse of design for ease of manufacturing, reliability, improved safety... Once it's adopted all the vehicles will have it.

Safety feature to ensure the turn signal can be seen, so it's not washed out by the DRL.

Exactly right. More information here. Jalopnik

Ok After reading this, I find myself looking at every vehicle and counting how many vehicles I see with this, each trip.

Great explanation why DRL have to turn off with turn signals from members and jalopnik but it still looks dumb!
