The function of the rear fog lamp of a car
The rear fog lamp of a car is a safety device specially designed for low visibility environments. Its core functions are as follows:
Core function
Youdaoplaceholder0 Penetrating warning
It adopts high-brightness red light source, with a penetration power far exceeding that of ordinary taillights. It can significantly enhance the vehicle's ability to be recognized by traffic participants behind in low visibility environments such as fog, rain, snow, and sandstorms (usually less than 100 meters), and warn to maintain a safe distance.
Youdaoplaceholder0 Reduces rear-end collision risk
Strong light warnings can significantly reduce rear-end collisions caused by insufficient visibility.
Design and Usage Specifications
Youdaoplaceholder0 Installation location:
It is located within a height range of 35cm to 1 meter from the ground at the rear of the vehicle, ensuring that the light avoids thick fog/dust at high altitudes, effectively illuminating the road and warning the rear.
Youdaoplaceholder0 Configuration difference
Some models (especially European ones) are only designed with single-sided rear fog lights, while others support double-sided or later modifications.
Youdaoplaceholder0 Enable conditions
When visibility is less than 100 meters, it must be turned on (low beam headlights and outline lights should also be turned on at the same time).
When visibility is between 50 and 100 meters, the vehicle speed should be no more than 40 kilometers per hour and the distance between vehicles should be over 50 meters.
Use misconceptions alert
Youdaoplaceholder0 Cannot be replaced by hazard lights : Hazard lights have weak penetration and the turn signal fails when turned on, which can easily cause misjudgment.
Youdaoplaceholder0 Do not use in non-severe Weather : Strong light may cause glare to drivers of following vehicles, increasing risk.
Iv. Youdaoplaceholder0 Operation prompt
The switch positions vary greatly depending on the vehicle model (such as the light knob, the center console or the screen menu). It is recommended to familiarize yourself with the operation in advance to avoid panic in an emergency.
Youdaoplaceholder0 Key summary : Rear fog lights are the "red alarm" in low visibility, and their core value is to penetrate environmental interference and force the attention of vehicles behind, rather than illuminate the road. Correct use can significantly enhance driving safety in bad weather.
The solution to a faulty rear fog lamp is as follows:
Youdaoplaceholder0 Check the damage of the fog lamp : First, you need to check the specific damage of the fog lamp. If the fog lamp is only loose, you can try to re-fix it. If the fog lamp mirror surface is cracked or the bulb is damaged, it needs to be replaced.
