How long will the battery last if the brake lights are on?

[Gage]

If the brake lights are left on overnight, the battery will be drained. Below is a detailed introduction to car lights: 1. Signal lights: These include turn signals (hazard lights) and brake lights. Proper use of signal lights is crucial for safe driving. 2. Turn signals: These are activated when the vehicle is turning and flash intermittently to alert vehicles and pedestrians in front, behind, and to the sides. 3. Brake lights: These are very bright and are used to inform the following vehicle that the front vehicle is slowing down or stopping. Improper use of these lights can easily lead to rear-end collisions. 4. Night driving lights and width markers: Driving lights, commonly known as headlights, should be used appropriately by switching to low beams when meeting another vehicle and promptly switching back to high beams afterward to extend visibility and compensate for reduced visibility during the encounter. Changing between high and low beams should be used to signal when passing through intersections or overtaking. Width markers, commonly known as parking lights, are used at night to display the width and length of the vehicle.
