Illuminating rings around lights

Does anyone know what are the illuminating rings around headlight and DRL in the headlight console. I tried searching but could not find what these are called?


Are these rings just reflectors OR separate lights?


Recently my passenger side DRL lamp went out. At the same time I noticed that both the rings around the lights are not illuminating.


Is it just a coincidence that all three went out at the same time or are they connected in any way?


I found the replacement lamp for DRL but where do I get those rings and how do I replace them?
