Bulb warning relay gone insane? Or?? 200 1977

So here's the scoop: parked the car. All was good. Came back 5 minutes later, my entire right side parking lamps were out (front, tail, AND the rt. license plate) _except_ the rear side marker (it's using the same ground as the rear, so that's ok). To top it off, no instrument panel illumination as well. What the hang happened in those few minutes I was in the store? Gremlins? Can a failing bulb warning relay kill an entire half of a car along with the afore-mentioned guage lighting? BTW, the relay does indeed let me know that half the car is dark....

Thanks much,
Rob

    Check the fuses. The front/rear park lamps are fused seperately left to right. I believe the instrument lights are also fused with the right park lamps. When mine blew, (right park lamps and inst lamps) I found the little white lamp above the rear ash tray had fallen out and grounded on the metal bracket for the seat belt catch. Also, these fuses can develop hairline cracks and lose contact. Another gremlin is corrosion on the fuse ends.

    I don't think it's your Bulb Failure Sensor. It wouldn't kill one side of the car or the other. The fact that it is telling you that those bulbs are not working is showing that the Sensor is working.
    Sounds like you have a large grounding problem somewhere. Check grounding strap from Valve cover to Firewall.
