What to do if the low beam light is not displayed on the dashboard?

Vehicles are designed this way. When driving normally with low beam lights, there is no low beam icon on the dashboard. Here is some relevant information about low beam lights: Definition: The illumination distance of low beam lights is approximately 30-40 meters. According to experiments: When driving at 55 km/h at night, if you immediately apply the brakes upon detecting a situation, the stopping distance is exactly 30 meters. This means that if you stop immediately upon detecting a situation within the low beam's illumination range, there will be no gap between the vehicle and the object. Function: Additionally, although low beam lights have an illumination distance of about 30 meters, they have a very distinct beam cutoff line. Most measured low beam lights of cars have an illumination distance of 30-40 meters, with the beam cutoff line at around 12-18 meters. The area in front of the beam cutoff line is brightly lit, allowing clear identification of objects, and a clearly visible illuminated area of 2-3 meters in diameter on the ground. The area from the beam cutoff line to 30-40 meters mainly relies on ground-reflected light. This area can distinguish brightly colored objects, but stationary dark-toned objects on the road are difficult to detect.
Last time I was driving, my low beam light wasn't showing on the dashboard. At first, I panicked a bit, but then I learned some simple checks: First, see if the actual light is on. If the low beam itself is working fine, it's likely an issue with the dashboard circuit or sensor. If it's not on, start by checking if the relevant fuse in the fuse box has blown—it's usually located under the steering wheel and easy to find. Next, try adjusting the dashboard settings or restarting the vehicle, as that can sometimes fix the issue. If none of these steps solve the problem, it's best to visit a professional repair shop for a diagnostic with proper tools—don't push through, as driving at night with poor visibility can be dangerous. Regular car maintenance can help prevent these minor issues.
