I just bought a 91 GTA and the fog lamp indicator bulb (the green one) doesn't come on when the fogs are on. Does anyone know the part number for this tiny little bulb. For those that don't know what it looks like, I attached a picture.

 

that is just an LED diode-radio shack or other electronic part store should have one,though you will need to remove the old one from the black plastic holder and install the new.LEDs don,t burn out from use,but they can be damaged if voltage applied without dropping resistor in circuit.The LED can be tested with a 9-volt battery and a resistor of ~500 ohms in series-also LED is polarity sensitive,will only light connected correct polarity.
