WTB cannot remember
I want to buy the switch where you can turn the head lights on and off manually on the Canadian C5's. It was advertised awhile back but I forget by who.

You mean defeat the twilight sentinel or keep them from coming on at night or in a building?
Depending on the year of the car you could have a few options.
Earlier models (up to around 2000) you can pull the sensor in the center vent of the dash and remove the wires and put about a 5k resistor on the wires instead. I don't know the exact year but the early Canadian cars were fixed and this is the only way to defeat it.
Later models you could do the same thing or find someone with a techII and turn off the export setting which should make a twilight sentinel setting in the options on the DIC appear so you can select which way you want it. If you are interested in this I could check the manuals and see when the BCM option became available to set this. The only part I don't know is if changing this would do something like default the car to miles when you start it.
If the car was imported then it should already have a setting in the options of the DIC to turn it off.
If you search the C5 tech forum for defeating the twilight sentinel you should find lots of info.

Islandman is right If you have a Canadian C5, and you keep it in your garage as I do, every time you start the car, your headlights pop up. As you know, the gear in the headlight motor is prone to failure as one of mine did. On the Cdn car, you cannot bypass this event on the DIC (U.S. cars you can). 99 times out of 100, I don't need my headlights, thus the premature failure of this gear.
OK, here's the work around. Remove relay # 44 in the passenger footwell fuse box (see details of location in the manual). I did this in 5 minutes. The only downside is that you have to turn your headlights on yourself. Oh, thats not a downside at all!

This applies to Canadian cars only. The fuse thing only works with 2001 and up I believe. In your case, you have to go the resistor route.
Twilight sentinel can be turned on and off using the D.I.C in all U.S. based cars.

Kinda of miss the pop ups now in my '05 but at the same time glad I don't have to worry about the plastic gears.
