headlight not very bright

I dont know if Id agree with that. From what ive read, 4300k is one of the best for visibility...

Yep the 5.5k will actually reduce white levels and in turn reduce visibility. I have no issues seeing at night. You could always add some fogs but I'm personally not a fan.

Wow, i dont think ive seen a Z with fogs...

Which is a good thing in my book.

Human spectral reception generally peaks around 5300-5600k.

Nope. 4300k is definitely towards the yellow end, ~5000k is what most people will perceive as white.



Taking knowledge of color temperature from HID ads is generally unwise.

The Z got 4300K lights because they look white against moonlight, which is generally in the 4000-4400K range(For reference, daylight is generally in the 5-7000K range)...this was done to reduce complaints by other drivers about "blue" headlights.

Most people are going to notice a nighttime visibility peak around 5300K, which is still in the "mostly white light" range.(side note:this is of course hard to measure since the color scale does not factor in colors not in the color temp scale, and almost every light source is going to include "off" colors...part of the reason identifying a "white light temperature" is very hard to do)
