If the brake light comes on when applying the brakes, either the brake fluid is low in the master cylinder, or a brake bulb is burnt out.

If the brake light is always on or comes on randomly the e-brake cable is either too loose or too tight, but since the other lights are coming on randomly then I'm guessing you're experiencing the joy and wonder of mazda's cold soldering.

The parking lights are turning on, or the idiot lights??? The parking lights would be the 1st step on, on the headlight switch and luminate the exterior corners.

But either way, anything under 12.6 volts means there is not sufficent power from the alternator to run the car. So either your alternator is bad or mis-wired

Sorry for bringing back this dead thread, but I have a similar problem and
thought I should just use this one.

Just recently, my brake warning light comes on whenever I start up from any
gear. If I accelerate up to a certain speed and let off a bit to keep a constant
speed, the light will go away.

I thought it was really weird because it's never done this before. Any thoughts?

As already described above, the BRAKE warning light comes on if the brake fluid is low. You should've checked that before posting, but it doesn't sound like you have...
