Can someone please tell me if there is a diffrence between 04-06 and 07-08 Headlights. Or are all the headlights the same thank you......

 

I think the shade of orange got deeper, too. You're a little bit off with the model years... it's 04-05, then 06-08. Yes, there are differences. Simplest things to look for are the black trim around the orange side reflector got thicker, and the projector lenses (for the low beams) got fresnel-like rings on their surface.

 

The orange reflectors are thicker and slightly longer. I would like to see pictures of the projector lenses differences if possible between the 04-05 and the 06-08.

 

Are there any YELLOWISH HID type for the TSX sells anywhere?
I'm looking for a totally YELLOWISH D1S bulb type..Does anyone know where I can get them?

 

And by yellowish you mean something like 3000K? These are usually suggested for foglight use only. OEM are 4300K which is white and your only other option would be to drop lower on the scale into 3000K which I would not recommend unless this is a pure show car and not driven on the street. As for the differences from 04-05 and 06-08 you also have the ballast slots under the headlights that are different since the 06-08 ballasts sit differently on the light.

 

I have seen YELLOWISH HID before but I wasn't sure the temperature scale, they looks nice though. Its different from regular headlight color, its way deeper yellow color.
Does this color exist on HID color temperature scale?

 

3000k is a deeper yellow, and fairly popular for fog bulbs...

 

Tbh it would depend on what you're doing. 3000K is on the scale to what most yellow HID fogs you see are driving around, that's what I am getting. But for headlights I wouldn't recommend it and most people don't. For practical driving and use I wouldn't do it. The people you see who do it do it strictly for looks. Also they may have their headlights tinted/filmed over or might be running yellow tinted bulbs like Nokya. I wouldn't do it personally but to each their own. If you like it then go for it but it won't be as good as stock fyi.
