I finally figured out how to disable my Auto Headlights for around $30 and stil be able to use auto mode!
This is how I did it.
1) I purchased a new headlight switch ($25-35 Rock Auto). AC Delco #84201596 W/fog lights, #84192536 W/O fog lights.
2) I removed the 4 screws holding the back cover on and using an eye glass screw driver I released the 6 tabs holding on the cover in place and removed it (fig.1)

Using the same screw driver I pried off the Printed Circuit Board (fig.2)

Be extremely careful taking off PCB. There are 2 copper contacts on the underside, (they are very delicate),
that are not attached to anything and might be stuck to the PCB (fig.3).

I had to use a tooth pick to put one back where it belonged.
3) Using a 3mm Ball Burr on my Dremel I made a new Indentation/seat on switch (fig.4 before).

Now when I turn switch off it stays in the off position. NO MORE HIDs firing up every time I unlock my car. And I can still use the swtich as it was intended.
4) I opened hood and using the appropriate tools (fig.6)

I created as much slack in cable as I could and disconnected cable at the hood release inside car. I bent the cable down 90 degrees and it popped off. I didn't try but you might not have to disconnect cable.
5) I removed the 3 bottom 7mm screws of the Panel Knee Bolster and using a plat blade trim tool I released 3 of the Pain In Ass clips on left side ( fig.7).

I have small hands some 3 gave me enough room to reach in and compress the 4 locking tabs and remove the switch.
I compressed the locking tab a removed the electrical connector and installed new switch (fig.8)

6) I put Bolster back together and reinstalled hood cable. Connecting cable was a bit tricky but if I can do it so can you.

Acree;
1) my bulbs are D5S not D3S
2) I bought the car used so no 3yr. warranty
3) I purchased 7yr 100,000 miles bumper to bumper coverage. Under "Not Covered Items" is LIGHTING

That bright flash is the igniter igniting the gas inside the bulb. After that the ballast takes over and controls the amperage or voltage to keep gas burning. Hopefully in the near future the price of my bulbs will come down and won't care as much if they burn out.

There is a spring but if you remove it the switch will Not lock in place. See Fig.5, the tab with the ball on the end has the spring tension on it. It locks into the indentation and stops the switch from rotating.

If used on the street please be aware that daylight running lamps are required by DOT regulations and you could be fined by local law enforcement.
My car does not have DRLs. I set the light switch to automatic and as soon as I pull out of my garage the photo cell senses it"s daylight and turns off all the lights.
