What kind of light is the rear bumper light?

The light under the rear bumper is a fog light. There are also turn signals. Fog lights are installed on the front and rear of the car to illuminate the road and remind the front and rear vehicles to maintain a safe distance when driving in rainy or foggy weather. The visible range of vehicle headlights is generally only within 30 to 50 meters, while the visible range of fog lights reaches about 100 meters. Function of fog lights: Fog lights are needed in foggy or rainy weather to make other vehicles see your car, so fog lights require high brightness and penetration. Ordinary LED daytime running lights and headlights cannot meet this requirement. Precautions for driving in fog: When visibility is less than 1 kilometer in foggy weather, you must turn on the headlights and rear fog lights. Turning on the headlights is not only to see the car in front, but more importantly to remind the car in front. Otherwise, the car in front may have difficulty noticing a car behind when changing lanes in heavy fog, which can easily cause a rear-end collision. Do not turn on the high beams at night in foggy weather. Because the high beam is designed for wide-area illumination, it can easily cause scattering in the fog, creating a scattering light cluster in front of the driver's eyes, making it appear all white and actually making it harder to see ahead.
The rear bumper lights generally refer to the lamps installed on the rear bumper, such as reverse lights and rear fog lights. As a seasoned mechanic with over a decade of experience running an auto repair shop, I can tell you these lights serve specific functions on most vehicles: the reverse light automatically turns on when the car is shifted into reverse gear, helping illuminate the rear, especially useful during nighttime reversing or in garages; the rear fog light is red and is activated in foggy, heavy rain, or smoky conditions to ensure vehicles behind can clearly see your position and avoid rear-end collisions. I’ve seen many car owners neglect these lights—they don’t replace them even when they burn out, resulting in expensive repairs after backing into objects. I recommend regularly checking the functionality of these lights—a simple way is to turn on the light switch yourself or ask a friend to help inspect them. Replacing bulbs is usually inexpensive, costing just a few dollars, but if an LED module is damaged, it’s best to seek professional service. Never delay repairs—these small details are crucial for everyday driving safety.
I'm a young car enthusiast, and rear bumper lights on my modified car refer to those additional lighting fixtures at the back. From my experience, they mainly include reverse lights and rear fog lights: the reverse lights emit white light to illuminate the path when reversing; the rear fog lights flash red in bad weather to enhance visibility. I've also installed LED reflector strips myself, which not only look cool but also help warn others. Once, my buddy had a light failure and scraped the wall while reversing, costing him quite a bit. Since then, I've made it a habit to check them monthly. Changing bulbs is pretty easy—most cars just require removing the protective cover. But remember, don’t modify them recklessly in ways that affect the original design, as it could violate traffic regulations and get you fined by the police. Always pay attention to how others react on the road to ensure your lights are functioning properly.
As an ordinary person who has long been concerned about driving safety, the rear bumper lights are crucial safety devices, mainly including reverse lights and rear fog lights. The reverse lights provide illumination when the vehicle is backing up, helping the driver see rear obstacles and reduce blind spot risks; the rear fog lights enhance rear visibility in low-visibility conditions, preventing rear-end collisions. Many car accidents are caused by faulty lights, so I recommend checking these lights during every vehicle maintenance or car wash to ensure they are functioning properly, replacing bulbs or repairing wiring if necessary. Addressing these minor issues early can ensure safety during nighttime or adverse weather conditions.
