Looking for pics of pdc switch. Help? Trying to see if feasible to use stock pdc switch to power driving lights. REALOEM only shows the blank cover. Thanks!

 

I can't address your question directly, but here's a suggestion. Since the flat tire reset button fits exactly into the space, consider using one of those. You already have one in your car, so you can take it out to test its electrical behavior. My guess is that if you will be able to connect it to a latching relay to turn it into an on-off push button for the lights. Of course the icon would be wrong but it will probably wipe off with acetone.
