Where to Check the Brake Lights?
2 Answers
Methods to check the brake lights are as follows: 1. Find a reference point, preferably at night when the lighting is strong, using a wall as a reference. 2. When stepping on the brake pedal, the light will be directly reflected on the wall. Observe the light's response and intensity through the rearview mirror to determine if the brake lights are functioning normally. 3. If there is no flickering of the light when stepping on and releasing the brake pedal, it indicates a problem with the brake lights. 4. If the left light is dim and the right light is strong, it means the left brake light is damaged. Reasons for the brake lights not working include: 1. Brake switch issue. Poor contact of the switch behind the brake pedal can cause the brake lights not to work. 2. Brake bulb issue. Mainly due to the bulb itself being faulty. 3. Brake system issue. If the oil level in the brake fluid reservoir is too low, it will cause the float-type sensor to prevent the brake warning light from illuminating or staying on.
Every time I drive, I regularly check the brake lights by stopping in an open area like in front of the garage, turning on the ignition without starting the engine, firmly pressing the brake pedal, and then asking a family member or friend to stand behind the car to observe if the lights come on. If no one is around, I get out of the car and repeatedly press the brake pedal from the driver's seat, using the reflection from the side windows or the rearview mirror to check the changes in the taillights. The brake lights are usually located at the very bottom of the trunk lid or in the corners of the bumper, bright red and easy to identify. If the lights don't come on, it's often because the bulb is burnt out—you'll need to open the trunk lining to find the socket and replace it. Occasionally, it could be a blown fuse, in which case you should check the corresponding label in the engine compartment's fuse box and replace it. This is a matter of driving safety; neglecting it could lead to serious consequences like a rear-end collision. I make it a habit to quickly glance at them every month when I wash my car to avoid trouble.
