Did you try driving the car from the left seat?  Ha haha!! 

These flashers are supposed to have some kind of feature so you know if a bulb is out?  What happens?

Tried that but cops didn't think it was funny. Seriously I got home today and pulled the switch apart and filed the contacts with a nail file and bingo all is working. Thanks.

Filing is not good either.  You can remove the most part of the built-up corrosion, but you should never file or sand away the metal of the interface.  Use a good contact cleaner instead.  My favourite is  DeOxit D-100.

Too fooking late for that. Already filed it. .

In any case, you don't need to "wire" the flashers into the car, you only need to connect or orient the flasher into the existing wires correctly, and some of the new flashers require one extra  connection to the chassis.
