That's them! And with a diode, you can make them stay on with the lowbeams as I've done (note, crappy photo)
But in some European countries, the Euro version of the Volt actually has them on by default with the lowbeams. They're actually decently bright, I'm considering making a circuit to lower their voltage when my headlights are on so they're more accent lights rather than complimentary lights to the lowbeams.
Making Daytime Runnig Light (DRL) LEDs stay on with headlights
Didn't have to kill any diodes only a couple of tap splice connectors to accomplish the same effect!
