What are the reasons for brake lights not working?

Reasons for brake lights not working: brake switch, brake light circuit, brake light bulb, circuit fuse failure. Solutions for brake lights not working: 1. Replace the bulb; 2. If the brake light switch is faulty, all brake lights will not work. During inspection, you can use a wire to connect the brake light switch. If the brake lights turn on, it indicates the switch is damaged and needs replacement; 3. If both the bulb and switch are confirmed to be working properly, check the fuse. Some cars do not have a separate brake light fuse and share one with other electrical devices. In this case, check the operation of other electrical devices in the car, identify the non-working ones, and replace the corresponding fuse.
I remember last time when my car's brake light wasn't working, I was really panicked because others couldn't see my stopping signal, which was too dangerous. The reasons are basically a few types: the most common one is the bulb burning out, the filament breaks and the light goes out directly; or the fuse is blown, just find the corresponding position in the fuse box and try replacing it simply. Wiring issues are also quite common, such as aging wires causing short circuits or breaks, or loose plugs leading to poor contact; the brake switch is near the pedal, if it's worn out and fails, the light won't come on. I've also heard that unstable voltage can burn out bulbs, especially when the generator regulator malfunctions. This can't be delayed, hurry to the repair shop for a check. By the way, during regular maintenance, ask the technician to check the lights to avoid emergencies. Safety first, replacing a new bulb isn't expensive, don't save on this small cost.
Hey buddy, don't take brake light failure lightly. I know young drivers don't want to waste money, but safety comes first. Most likely it's just a burnt-out bulb from prolonged use - replacing it costs just a few dozen bucks. Or it could be a blown fuse - just swap in a new one from the front fuse box. Wiring issues like loose connections or damaged short circuits can also cause problems. If the brake light switch is faulty, the pedal won't trigger anything. As a newbie, I've even experienced voltage issues causing frequent bulb failures. My advice: first check fuses and bulbs yourself, be careful not to tamper with circuits, and visit a professional shop if stuck. For prevention, just glance at your rear lights before driving each month - saves both hassle and cash.
The main issues causing brake lights not to work include bulb burnout, fuse blowout, wiring faults, or poor contact. First, check if the bulb is broken or blackened, and replace it promptly. Second, if the fuse is blown, refer to the owner's manual to replace the corresponding one. Third, short circuits or breaks in the wiring harness can affect current flow, so check the tightness of the connectors. Fourth, abnormalities in the brake switch or relay can cause the lights not to illuminate. These situations can easily lead to rear-end collisions, so it's recommended to seek repairs as soon as possible. Repair shops will use a multimeter for diagnosis to ensure the circuit system is functioning properly. Regular attention to light maintenance can help avoid risks when driving at night.
