Well before I learn how to use a volt meter I'll try some different bulbs.

The bulbs you should be using will have 2 filaments, as you noticed. This also means the bulb will have 2 metal contacts in the base, and the locating pins sticking out from the sides of the base are NOT symmetrical. So the bulb can only go in one way. If you look into the bulb socket, in the car, you will see 2 pins that will line up with the bulb contacts when it is inserted. Get a Multimeter, and set it on 20 Volts range. Put the emergency flashers on, but leave this bulb socket empty. Then take the multimeter probes, the black one to the lamp housing, and the red one to carefully touch one of the 2 pins in the socket. The multimeter should jump from 12v to 0v in time with the flashing of the other bulbs. If not, carefully probe the other pin instead, with the red probe. If you get one of them to jump to 12v and back to 0v, then power is getting to the pin - great! This is fault condition "A". If neither gives a jumping voltage, you have condition "B".
Condition B means the fault is in the wiring or back of the socket.
If condition A, than the pin in the socket is the problem. It either needs carefully cleaning (With all systems turned off!), or the pin is sticking in. This requires a new socket!! However, adding solder to the bulb contact will fix it.
Let us know what you find!
