Is this an indication of a bad relay? If so which one?
Thanks! |

Nope. It's most likely a mis-wiring at the taillight buckets, or having the wrong bulbs in the wrong sockets.
Unless the brake lights are on any time the ignition switch is on--in that case, you put the washer on the brake pedal pushrod on the wrong side of the lever on the brake light switch. --DD |

Bad ground at the tail lights.

What is strange is that they were working before I went out one night and was turning the lights on and off for my kids. I didn't change anything. I'll check the ground-thanks everyone. Any other ideas welcome!
Also, I noticed that with the ignition off, and the lights turned on the brake lights are on. If I step on the brakes, it makes the gas needle move to position, and the voltmeter moves to on. |

I double checked the connections on the rear lights, all terminals were clean and connected properly.
Could the headlight switch be the problem? |

The latter sounds similar to some behavior we see when fuse #8 or #9 pops.
