Need help identifying which light

[Time2Panic]

I have a 2006 RX400h. At the top of the housing of the bright lights there is a very small and dim light. It runs dimly when the low beams/parking lights are on. The drivers side bulb is out but I didn't see the ID of the bulb for reorder and I don't know what to call the light to search for the replacement. Can anyone help?

Is it the day-time running light?
