I am a bit worried about putting HID in my altezza, as ALTEZZA headlamps are designed for Halogen Bulbs not for HID. There could be a problem with beam gathering and the diffused light may dazzle oncoming traffic. I am not sure whether it is legal to use HID.
There is a solution: HID retrofit into dual round projectors. see below:
A lot of ppl look after a nice bule light output and go for the HID >8000K. However, 8000K has an approximately 2500lm light output and less output compared to the 6000Ks and 4300Ks. 4300K has the best light output (approximately 3100lm) but light appears fairly white, not bule.
The 4300K HID and projuectors can be expected to achieve the best result: bright and wide light output + beautiful light cutoff + cool bule light.
There is a US company can do HID retrofit for LEXUS, their products looks very nice, also inculding black housing headlights and Demon/Angel Eyes.

Here are two pics of their projector headlights for IS300. However, not sure whether they can be fit to ALTEZZA.
Anyone have any idea about this?
