Pre-2011 DRL Ideas Please help/Clarify
Yeah I think I might go with the IJDMtoy ones because of how everyone with the VLED's are having reliability issues. But as far as your high beams go, What happens when you turn on the high beams? does the 9005's just don't turn on? I have the HID/AFS headlamps so my low beams are bi-xenon.

1. The inner 9005 halogen bulb will light up (this is the same bulb used for DRL)
2. The outer D4S will be tilted up by the AFS system
So even if you replace the 9005 bulb with an LED kit, the HID/D4S will still provide some illumination, you just lose any extra light output the halogens may have provided. Personally I just had the dealer turn off my DRL. I value my high beams as over 50% of my driving is after dark.
That is only true on 06-10 models though. 2011 factory HID's dropped the Bi-Xenon function of the HID's.
(I know this thread is related to pre-2011's, just thought I'd throw that out there).

The LED DRL's will still light up whenever your high beams are engaged, but they don't emit much usable light so you effectively lose your secondary high beam. However, because you have bi-xenon lowbeams you retain some high beam functionality, but it won't be nearly as bright. It's a tradeoff.

Maybe someone with a 2011 can chime in, I guess.
2019 EDIT: Came across this old thread, and this information is incorrect. 2011+ HID's do have bi-xenon. No idea why the Lexus docs said differently.

Thanks Jeff, that does clear some things up.
I was curious to see just what my lights do under certain conditions, so I went and tested. (I have OEM HID headlights, LED DRL, no parking lights)
Should have taken video...
If I turn my headlights on ---> LEDs turn off
If I have only my DRLs on and flash high beams ---> LEDs flash off, HIDs flash on
If I have my low beam HIDs on and flash high beams ---> LEDs still off, HIDs flash "brighter" (up)

I know Lexus.com still lists them as Bi-Xenon, however it is often wrong/slightly wrong about specs/options you can get. In fact it even lists the IS250 as having dual-piston front calipers. No 2IS has ever had dual-piston calipers (the IS300 did). I based my information on the NCF books, I don't have HID's on my 2011, so I haven't had a chance to check this personally, but this is what I based it on.

I'm asking btw, not rhetorically.
EDIT: I saw on post #18 its supposed to do both. I will do some more testing this weekend if I can find the old halogens...

So, you're saying that with low beam HIDs on, when flashing the high beams from the column, my HID's should do nothing and my LED/DRL should only function as the high beam? Why does the picture 06-10 say the projector style HID is used for hi/low beam?

Now I'm wondering what the deal with the decoders is. If my polarity was wrong, I don't see them working at all. I need to research what the decoders do, because my DRLs indeed shut off under "high beam", but have no problems immediately coming back on. Odd huh?
Thanks for clarifying.
