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

If the brake lights stay on overnight, the battery will be drained. Here is a detailed introduction to automotive lighting: 1. Signal lights: Including turn signals (hazard lights) and brake lights. Proper use of signal lights is crucial for safe driving. 2. Turn signals: Activated when the vehicle is turning, they flash intermittently to alert surrounding vehicles and pedestrians. 3. Brake lights: These are highly bright and inform the following vehicle that the car ahead is slowing down or stopping. Improper use of these lights can easily lead to rear-end collisions. 4. Night running lights and width indicators: Headlights, commonly known as high beams, should be dimmed to low beams when meeting another vehicle and switched back to high beams afterward to extend visibility and compensate for reduced visibility during the encounter. Flashing between high and low beams is recommended when approaching intersections or overtaking. Width indicators, commonly known as parking lights, are used to display the vehicle's width and length at night.

What are the reasons for abnormal noise when braking?

Abnormal noise when braking may be caused by normal ABS operation, safety reminders, loose chassis components, or unstable brake discs. Precautions for braking are as follows: 1. Coasting in neutral downhill with brake control: Many people may choose to coast in neutral downhill and use the brakes to control speed, thinking it saves fuel, but this is actually a misconception. Coasting in neutral downhill and using brakes to control distance for a long time may lead to overheating and failure of the brake system, resulting in accidents. When encountering a downhill slope, you should shift into the appropriate gear based on the speed and use engine braking, occasionally supplemented by braking. This method is both safe and extends the life of the brakes and should be kept in mind. 2. Braking hard when a tire blows out: Some drivers may have encountered a tire blowout. The common instinctive reaction is to brake hard in an emergency. In such a situation, do not panic. Hold the steering wheel firmly, try to control the direction of the car to prevent loss of balance, and slow down gradually. For manual transmission models, you can downshift step by step or shift to neutral, release the accelerator, and gently press the brake repeatedly until the car comes to a slow stop. 3. Braking at traffic lights: This is a situation encountered and performed daily while driving. Many people tend to brake directly when encountering a red light, which is actually not reasonable. When waiting at a red light, if the waiting time is around 10 seconds, you can slow down and use the brakes to control. However, if the red light lasts more than 30 seconds, this operation becomes very unreasonable. In this case, you should choose to engage the handbrake and shift to neutral to avoid the balance between the brake and transmission, which could cause damage to components and harm the car.
