I don't mean that in a cut-every-wire sense. It really bothers me to not be able to completely turn off my lights (for example, in a parking lot at night where I want to keep my car running). Is there a method that enables the headlight control switch on the steering wheel column to completely turn off the lights? I've seen threads about disconnecting one of the harness pins to disable DRL, but nothing like this.

On a side note, I know the newer Camry's can do this, so maybe there's an Avalon workaround? Any help is appreciated.

I don't know if this will work. But the old Chevy Astro vans if you set the parking brake the DRL would shutoff.

I'd like to point out that I may need to do this soon so will probably be cutting the wires to DRL... as well as possibly doing independent fog light modification.
I also want a switch control on drl. Don't cut them yet unless you are in a rush. I am tracing the wires (no wiring diagram, so working backwards). Maybe you can take out the pin from the harness instead. Let me see if I can figure out by comparing with our camry (though colors will be slightly different). As for fog mod, speedkar9 has a thread and video on it.

I've been trying to make sense of the wiring diagram as it pertains to the DRL.
It appears that there is a 7.5amp fuse, which supplys power via a red/blue wire to a connector that then becomes white/red wire. That powers 2 DRL relays and grounds via a white/black wire at the front of the right fender. It is called grounding point EA on the diagram and the W/B wire should be coming out of a grey connector (EA1 with 11 wires) just in front of the coolant overflow reservoir. The W/B wire going into that connector may actually be 2 W/B wires (1 from each DRL relay)
I think what I would do is try to locate that ground wire. Isolate it from any other ground wires it might be spliced in with. After re-grounding the others, check to see if the DRL are disabled. If so, I would install a relay to ground, controlled by a separate switch located anywhere convenient inside the car...ie. turning on the switch would cause the relay to ground the DRL circuit thus restoring the DRL function. Simply leave the switch in the ON position all the time until you want to kill the DRL.

I took a look at my Avalon today....The grounding point is hidden behind the coolant reservoir. Just pull up on the bottle and it comes off its' bracket...the ground bolt is then accessible. The DRL relays and fuses are in the box in front of the reservoir.

Any idea on how to change the DRL voltage to be say.. 4-5v instead instead of disabling?

Not sure if this is something you want to do, but I tried using LEDs for DRL/Hi-Beams. Without using any fancy decoders or adapters this completely disabled the DRLS (which are what stays on even if you put the lights in the off position). So at night time if you want to be parked with no lights you can turn it off and not have any lights, that being said you will also not have any DRLs if you leave the lights in the auto position and it is light out. That didnt really bother me, as with that car I could just leave the lights always on as they would auto shut off after 30 seconds or so with no key in the ignition. The LEDs as Hi-beams were great when I needed to go on back country roads. Additionally it is kind of expensive for a decent pair, unless anyone else has some cheap recommendations which have worked out.

I do have LED's however cannot put them in since they operate at 4-9v. They're too bright to put in my car.. hence my need to do a step down when running in DRL mode.
