i no theres a million articles about this topic but i was wondering what would be the best option for getting pure white lighting for my 5 series

 

If your car is 2004-2007 then I would try the MTEC V4's.

If your car is 2008+ then you have many options; 6W LED from Trinity Autosports, HID, GP Thunder.

This is all assuming you have xenon lights, and is limited to only my experience.

Word of advice, put information about what you drive in your signature so people have something to reference when answering you. Parts/options vary greatly depending on year/model/equipment.

 

2008 535i with xenon lights*

 

so did you read any of those threads included in the million you mentioned?

in all seriousness...since you posted later on that you have an LCI with xenon headlamps

Plug and play options:
Halogen: GP Thunders (not so bright in daylight)
LED; Lux Angel Eyes (visible, not as bright as the new OEM LED AE's, but still good IMO) or the 6W AE kit that's being sold by a vendor on this forum as well
HID: many out there to chose from, take a stroll thru the vendor section to find a good set of HID AE's (bright in daylight, some say inner circle is too bright and can drown out the xenon bulb at night and/or appear as if you have your high beams on...)


Not plug and play (requires you to open up your headlight housing)
Orion V2 LED rings: most evenly distributed brightness between inner and outter rings, most visible in daylight, as bright if not brighter than current OEM LED AE's
if you are not willing to do this install yourself there are members here that can do this for you (for an additional price of course)

a good amount of threads can be found regarding all of the above mentioned choices...GL with your decision

 

if interested we have our 6W angel eyes available for the LCI models: https://5series.net/forums/topic/115...-for-lci-e60s/
