Stock HID (white color or brighter lighting system) on the 2nd gen IS is using D4S bulbs, and only D4S. D4S is the latest generation of headlamp lighting standard. The AFS has nothing to do with the D4S standard. ASF is an aiding function to asist driver for better night time driving. In simply, it basically does turning the focal point of your headlamp upon your steering angle.

Yes, that sticker means that you already have stock HID (High Intensity Dischrage). The stock HID temperature is rated to be 4300k, which is a bright white. The stock HID is also a D4S bulb, not H11 (H11 is for halogen ONLY). Although it is white, it has the most lumens (most visible light) than any other temperature. People go with higher temperatures for different colors (i.e. 6000k = white diamond/blue, 8000k = blue and so on) but the higher you go, you lose more lumens (visible light). HID's are the lights you commonly see on BMW's and other luxury cars, although they are coming more and more common on almost all cars. That's what HID's are and now here's the difference:

Halogen uses standard filament to produce light, while HID's use different gases and metals to produce light. In HID's, it takes 20,000 volts to light up (excite) the gas in order for the gas to emit a light but after it is lit, it only takes I think like 35V to keep it runing. Since it runs at a lower wattage, this means that it will last a very long time (like 3x-5x longer than standard halogen bulbs). Halogen bulbs (the stock yellow colors you see only mostly every car) uses 55V to keep running and the amont of light it emits is far low compared to HID's. HID's emit 3x the light than halogens.

And as stated above, the AFS (Adaptative Front Lighting System) is not HID technology. Its a system used by Lexus that illuminates curves. For example, when you turn your car, the headlights will also turn at a certain angle in the direction your car is turning. This will help you see better because you will get light when turning and can see better in more directions. I think it turns up to like 15 degrees (right headlamp) and like 55 degrees (left headlamp) [I think its something like that]
Hope that helps. If you have more questions, PM me.

Thanks for all the information! I ended up going with Hella Xenon White for my DRL's. I just picked them up at a local Advance Autoparts for $45.00. A perfect match on the high beams, but still a tad yellow on the DRL's. Still waiting on my refractor 5-led for the parking lights.

Did anyone else have problems getting to the driver-side lights??? I moved the the windshield wiper fluid intake, but it was still nerve-wracking getting down to the bulb. I finally got it, but I have to do it again when my parking lights come in. My hands got pretty scuffed up.

I had the same issue, but was able to remove the bulb. It took a long time putting the bulb back in as you have to turn the bulb housing clock-wise and lock it with two wire clips. If someone have some pics on how to remove or install the bulbs, that would be great.

I've been itching for the 6000K color and I think I'm finally gonna pull the trigger on what looks like a good brand by the name of Garax. Price is reasonable at $89.95 shipped which I found on eBay. I will post feedback once job is complete. If anyone has feedback on this Garax please share. Thanks...
