please help me understand this headlights/halo stuff

[Professor]

good info! here is where i'm still fuzzy. the angel eyes is one bulb that lights up both rings per headlight? is the yellowish light bulb closet to my grill a different bulb then?

that crappy yellowish bulb looks easy to change out, however if this is not the bulb i need to change for the angel eyes than I have no idea what to change out.

Also, if i buy the Mtec's MTEC Ver. 3.0 LED ANGEL EYE BULB BMW E65 E66 E67 E53 X5 | eBay

do I than have to change that yellowish bulb so it doesn't look weird?

I attached some pics of my headlights. the first pic is no key in the ignition and the lights turn from 0 to 1 click to the right (so the markers come on). Next pic is the same light position but I turned the key till all the gauges came on. next pic is if i turned the light switch all the way on.

thanks for putting up with my need to understand how things that interest me completely work!
