If this is for an E46 I recommend the following:
DEPO Projector 46: upgrade to projector low beam with Angel Eye capability
DDM 55 watt HID kit: 6000K color temperature highly recomended
Umnitza Predator Orion V2: AE's include 60LED's per ring, super bright and look sick.
Most of this info can be found here, at CA Automotive
. I also am assuming you're in the UK which is why I supplied them as a possible retailer.
