The reasons for the right fog light not working include a blown fuse, a damaged bulb, or a wiring fault. Power supply of the fog light: The front fog light relay in a car is always powered by the battery voltage. When the fog light switch is turned on, the fog light relay will be energized. If the front fog light does not illuminate, it is necessary to check the fog light fuse, as it may be damaged. Additionally, the fog light bulb should also be inspected for any damage. Function of the front fog light: The front fog light of a car is installed at a position slightly lower than the headlights. Its main purpose is to illuminate the road during driving in rainy or foggy weather. In such conditions, visibility is very low, and the driver's line of sight is easily obstructed. The fog light uses yellow light, which has strong penetrating power, to maximize the alert to other vehicles and pedestrians on the road, ensuring driving safety.

What is the fuel consumption of the Luxgen 7 SUV?

The Luxgen 7 SUV has a fuel tank capacity of 75 liters, which is the officially announced data. Owners who have purchased the Luxgen 7 SUV can also check this information on the vehicle's configuration sheet. The Luxgen 7 SUV uses 92-octane gasoline, with a fuel consumption of 8.9 to 12.1L per 100 kilometers. A full tank can cover a distance of 620 to 843 kilometers. During daily driving, it is necessary to always pay attention to the remaining fuel level in the tank. This is usually observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the car manufacturer is measured from the bottom of the tank to the safety limit, and there is still some space from the safety limit to the tank opening. This space is reserved to allow for fuel expansion when temperatures rise, preventing overflow from the tank's safety space. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.
