Are the Tail Light and Brake Light the Same Bulb?
2 Answers
Tail lights and brake lights are not the same light. Here is some relevant information about brake lights and tail lights: 1. Brake lights and tail lights are not the same car light. 2. Since brake lights serve a warning function, they are larger and brighter than tail lights. 3. Tail lights are generally placed as close to the rear of the vehicle as possible and appear as a continuous white light. Here is some relevant information about car lights: 1. Lights are a very important part of a vehicle. Whether it's headlights or fog lights, the maintenance and care of car lights are crucial for driving. 2. Once there is a problem with the car lights, it not only affects driving comfort but also directly relates to driving safety. 3. Therefore, every car owner must pay attention to the maintenance and care of car lights and not wait until there is a problem to take notice. When the brightness of the car lights is insufficient or they are not working properly, it is essential to inspect and replace them promptly.
I just took apart the taillight assembly of my own car and found that most older models indeed use a dual-filament bulb to achieve two functions. The outer shell is transparent, but the two separate tungsten filaments inside work independently: the dimmer one serves as the nighttime running/parking light, while the brighter one only lights up when the brake is applied. However, newer models like my SUV have long adopted a split design—the brake light uses a more eye-catching LED array, while the parking light is a low-power halogen bulb. The biggest advantage of this redesign is that you don’t have to replace the entire set if one fails. Last time my brake light went out, I only spent 25 yuan to replace the right-side LED module, saving hundreds. Remember to have a friend press the brake pedal while you walk around the car to inspect it, otherwise, you might misdiagnose it as a taillight malfunction.
