I drive a 2003 525i g007923
After living for months with very very poor front lights, yesterday the driver light went out, which revealed a big mess.
My car has xenon lights package, I do not know if the picture confirms this.
AFter some reading and I understand a ballast is needed on each side, to power the xenon bulb. So I went to ask for xenon bulb replacement, and found a big mess courtesy of the previous car owner.
1) The xenon bulb harnesses had been removed to fit (glued with silicon) H4 blue halogen lights on both sides :thumbdwn:, which rendered poor performance, my low beams illuminated only 10 meters ahead at night
2) the h4 bulbs are of more than 35 watts, and the harnesses and wires were toasted, close to create a short circuit. I removed the h4 bulbs and taped the wires taped to avoid any contact, and need to take action now
3) adjusters are broken on both sides, low and high beam lights move loose, some other harnesses are toasted, have to replace them
4) I do not see any ballast on either side, nor see where to hold them, nor cables or harnesses to connect them SEE PICTURES
Since I think this will not be an easy or cheap fix and I want to take proper action, I dare to make these questions, please understand my absolute ignorance on the subject
a):dunno: do I need the ballast or are they hidden in this model? (honest ignorant question, do not flame me)
b)if yes, is it a good idea to buy used ones? or aftermarket ones?
c)were my headlights sets previously replaced and are not for xenon?
d) should I install h7 halogens on the low beam side? (and forget about xenon), i really have not seen how xenon lights perform
e) can i purchase all these parts separately?
thanks
