Disable DRL on 2011 with Halogens?
I just installed some 2012 LED/HID lights and I have everything working right except I can't seem to disable DRL's. The option isn't listed in the TechStream, or an older handheld scanner.
Anyone disabled it on the 2011 without HID?

I thought you didn't like the newer headlights 
. Congrats! It's weird the feature isn't there, I thought the '11+ non-HID cars used the same light setup as the '06-'10 non-HID cars.

He went with the 2011 lights because he did not like the fact he was using an AFS headlamp setup he had in the car but his car could not use it to its full potential.
Jeff and I were talking in private a few days ago regarding the TSB lights and actually managed to be able to order them; it was also because he wanted to get the correct lights for his car.

There are things I really like about the newer headlights, like the dark housing, and the nicer projector (it is nicer than the 06-08). I even like the LED, just find the LED section to look a bit funny when it's all off. That being said, once it was actually in my car, and not just looking at other cars, I find I like it more than I did before. I'll let it grow on me, it's already started.
But there were distinct advantages going from my 06-08 HID headlights to the 12 ones, including not having to deal with AFS, etc. However, one of the advantages was going to be that I would be able to disable DRL, so that the Bi-Xenon would work correctly, as on the 11+ lights, it's just piggy-backed off of the high beam wiring (on 06-10 HID's, the front controller had a separate output for it), but since I can't disable DRL, the Bi-Xenon solenoid is always getting a 50% duty-cycle from the DRL/High Beam bulbs, which may not be good for it, though it seems unlikely that it is. As it stands, when my headlights are off, my Bi-Xenon is set in high mode until I turn the headlights on, then it immediately drops to low beam. It doesn't really matter, since the bulb isn't on.
Also both my DRL and LED's are on at the same time, which isn't actually too terribly bad looking, but it isn't correct. I like to make things correct.
Everything is the same as far as wiring goes, but there is no DRL option in the menu. 
The old ones aren't orderable in Canada anymore, you can only get the new ones now. Maybe they still have stock in the USA, but I have a feeling it's all changed up.
Yeah I have a feeling once people find out the pricing on the 81145-53H12, you'll see more people doing this swap. It's basically 2 headlights for the price of 1.

wow, I know so little about lights that all I read was )(*%$HNO#
)*#*$&_VJOFJ:??>_$*
But personally, I love the way the 11' LED lights look when DRL are on, it looks sweet!

I just installed my lights, granted I have an ISF but i just went to my service advisor at Lexus, he hooked up his laptop to the OBD2 port and had the DRLs turned off in a matter of seconds and it was free. So just go by Lexus. If they can' t do it then it might not be an option for your car at this time.

Thanks for the advice, but like I said, I tried using a TechStream, TechStream Lite and an older Handheld, the option wasn't listed in any of them. I can adjust the other settings, but DRL is not listed. It seems like the option was removed on the 2011's, (though it is still listed in the repair manual... :|)

Sucks to hear the option had been removed from the '11's. It wouldn't be too difficult to rewire the high beam using a relay and the high beam output from the stalk.
