Just a few clarifications since dvo's post wasn't entirely accurate - here's what happens at each click of the headlight stalk:
- 1st setting (Off): The LED DRL's will be on when you are in drive. No parking lights.
- 2nd setting (Parking Lights): The DRL's will be on when you are in drive. The parking lights will be on at all times.
- 3rd setting (Low Beams On): Your parking lights and low beams will be on at all times. The LED DRL's will be off unless you engage your high beams (which in turn disables your fog lights if they are on - out the factory you can only have the high beams or fogs on at one time).
- 4th setting (Auto): 1st setting during the day, 3rd setting while at night.
However, could you clarify what you meant by bi-xenon low beam? Not sure what that is . . I have a 2010 but I already swapped out the OEM HID with a 6000k D4s low beam.. will I have any high beam functionality left after I put in LED DRL?
I agree

Thank you so much, that was exactly what I was wondering ! Extremely helpful

Bi-xenon is when your low beam also functions as a high beam by physically moving a shield that cuts off the top of your light beam (hence the term cutoff for the sharp line your low beams form when you shine them against a wall). By taking away the stand alone 9005 (bulb size) high beam and replacing it with an LED DRL you lose a considerable amount of high beam brightness, but you still have the bi-xenon functionality from your D4S HIDs. Swapping out to a 6000K high beam doesn't affect your bi-xenon functionality, but 6000K bulbs will bulb out less light than the stock 4100K ones. 6000K looks much cooler though.

I also read about it on google, but still doesn't quite understand it; how does cutting off the top of the low beam light make it function the same as high beam?
I've also noticed something weird. I now have 6000k d4s. Every time I turn low beam on, the light would turn vertically downward then back up and become straight ahead, but the blueish tint only appears when the light is pointed downward and disappears when the light is pointed straight ahead. Weird phenomena ..

The blueish tint that you see is the HID's warming up (they are blueish when firing up, then quickly turn to their normal color)

The parabolic lens also acts like a "prism" at different angles, which is why you'll see different colors at the edges of the lens, for instance, when it moves to vertically align them. It's just scattered light that didnt make it to the focal point.

Like others said, the lights go up and down when you start up the car as part of auto-leveling, which is a feature designed to prevent your lowbeams from pointing too high or too low. The blueish tint is probably a combination of two things: (1) your 6000K bulbs are more blue when they first fire up, and become whiter as they warm up. (2) the prism/flicker effect caused by the way the projector lens bends the light coming from your D4S bulbs. For example, you might notice blue flickers from oncoming cars (particularly BMWs and Acuras) when they hit dips in the road, but if the light is shining straight at you it's almost pure white. Below is a picture of my car with 6000K low beams and fogs demonstratingt he flicker effect. You can read the whole thread here: https://www.clublexus.com/forums/is-...fogs-pics.html
Just curious, how did you confirm you have bi-xenon?

I think I may have worded my previous post poorly - when your bi-xenon low beams are in "high beam mode" the cutoff shield is moved out of the way so you get the full, unobstructed beam of light from your D4S bulbs. The cutoff shield is of course there so you don't blind other drivers when in "low beam mode." Hope that clears things up.

Now here is what I don't get I still have a high beam light inboard of the HID light. and in the owners manual it also shows the high beam light. The manual lists the bulbs as follows
Headlights: high beam 9005, low/high beam(discharge bulbs) D4s, Low beam (halogen bulbs H11 here is a picture of my cars headlight.

Thanks thats what I was hoping happened but I couldn't tell for sure. I haven't been out on the open road in the middle of the night yet where I could really get to use the HBs.
