Around the brake pedal (front and back) are two switches, one to cancel cruise control (if your vehicle is so equipped) and another to lit the stop lamps whenever you press on the brake pedal. If you look down on it and depress the pedal, you'll see which one is pressed and is being released. Normally, the brake pedal switch is released (making a complete electrical connection and lights the stop lamps) whenever you press the pedal. The stop lamp stays lit whenever the switch is stuck (worn spring, corroded connections, broken push pin, etc.). If you can't identify which one is for cruise control and which one is for the brake, just go to a Nissan dealer and get a new stop lamp switch (for the 2000-2004 Nissan Frontier V6, it is part number 25320-75A0E) for about $15. You can then match it with the same switch mounted on your vehicle. They are normally easy to replace with only a wire connector to disconnect and a nut to loosen in order to remove and replace it.

The parking light stays on how am I sure the parking brakes are not on
Yes, on a 2003 Nissan Frontier, the third brake light should illuminate when the headlights are turned on, but it will only stay on when the brake pedal is pressed. This behavior is standard for most vehicles, as the third brake light is designed to signal braking rather than simply being a running light. If the light remains on without the brake pedal being engaged, it may indicate a wiring issue or a faulty switch.
fix the problem. if it says brake, it might also be the brake fluid level or brake shoes or pads.
Take out the two screws and replace one or both of the lamps.
The first thing to check is low brake fluid. A leak in the system or worn brakes causing the fluid to be too low is the most common cause for the light to be on.
To replace the brake light switch in a 2001 Nissan Frontier, first disconnect the negative battery cable to ensure safety. Locate the brake light switch, which is typically mounted above the brake pedal assembly. Remove the wiring connector and the switch itself, then install the new switch by reversing the process, ensuring it is properly adjusted to activate when the brake pedal is pressed. Finally, reconnect the battery cable and test the brake lights to ensure they function correctly.
