Wiring or what?

I have a '95 Jetta.. the speedometer light only will work sometimes (usually only when its cold and it turns off when the engine warms up). Is it the bulb? Is it wiring?
HEADLIGHTS: My right bright headlight wont work. The dim lights work and the left bright light works. I took it to Auto Zone and they tried 3 different bulbs.. none worked. Is it the wiring? Please help. Thanks![COLOR=green][FONT=fixedsys]

If it's just the speedo light, not all lights, then you have a bad connection. Probably where the bulbholder twists into the gauge unit. I believe each headlight has it's own fuse, both for high & low = four fuses. Check them first.
