Is It Normal for Only One Brake Light to Be On?
2 Answers
It is not normal for only one brake light to be on. Typically, there is one brake light on each side, and many vehicles also have a high-mounted brake light in the center. Here are the classifications of brake lights: 1. Gas Brake Lights: These use gas materials, such as halogen. Gas brake lights are technologically mature and inexpensive, but they emit radiation, contain mercury, and have glass casings that are prone to breaking, which can pollute the environment. 2. LED Brake Lights: Brake lights made from LEDs have no radiation or pollution and offer a long service life, theoretically up to 60,000 hours. This means the bulbs do not need replacement during the vehicle's lifespan. However, LED brake lights are more expensive, which affects their widespread adoption.
Buddy, if only one brake light is on, that's definitely not normal. Under normal circumstances, both brake lights at the rear of the car should light up simultaneously. This design ensures that drivers behind you can clearly see your braking intention under any circumstances. Imagine driving at night with one light out—the person behind might misjudge your actions, significantly increasing the risk of a rear-end collision. Based on my experience, this is usually due to a burnt-out bulb or an electrical issue, such as aging wiring or a blown fuse. I've driven for over a decade and encountered a similar situation—it almost led to an accident, but luckily, I got it fixed in time. I recommend you find some time to check it out soon. A simple way is to inspect the bulb yourself for blackening or use a multimeter to test the circuit. Safety first—don't delay too long.
