If you're asking because something *seems unusual*, specify what's unusual. For example:
* Are *only* the brake lights coming on? (If your tail lights aren't working, that's a separate problem).
* Are they excessively bright or dim? This could indicate a problem with the bulbs or wiring.
* Do they stay on *after* you release the brake pedal? This points to a serious issue like a brake light switch problem or a short circuit.
* Is there a grinding noise or other accompanying symptom? This could suggest brake system problems beyond just the lights.
* Did this start suddenly, or gradually?
Without more details, it's impossible to say if there's a problem. If something *is* wrong, it could range from a simple burned-out bulb to a more serious brake system malfunction. If you suspect a problem, it's best to have a mechanic inspect your brake system to ensure your safety.
