put hid's in my e36 and it was a doddle and looked good.
i now have a 2002 5 series, halo lights, i want to fit hid's to it but have been reading about faults coming up on the dash saying the lights are out? low power drain? so computer says bulbs in op?
also is there a need for an adaptor ring to take the bulb?
has anyone done this to an e39 with the halo lights?
do you have a list of the things i WILL need to get the job done
