Why doesn't the dashboard light up when the headlights are on at night?

The reasons why the dashboard does not light up when the headlights are turned on at night include a blown dashboard fuse or issues with vehicle settings. Blown dashboard fuse: If the dashboard fuse is blown, it will not only cause the dashboard lights to fail but also prevent the dashboard needles from moving. In this case, a new fuse needs to be replaced to avoid unnecessary trouble caused by the dashboard not functioning properly. Vehicle settings issue: This is how the vehicle is designed—the dashboard lights being too bright can affect driving, so turning on the headlights defaults to driving mode, while turning them off defaults to parking mode. The dashboard is a rigid panel or structural component used to install instruments and related devices. It can be categorized by type into screen-type dashboards, frame-type dashboards, passage-type dashboards, and cabinet-type dashboards.
I've been driving for almost twenty years and have seen this kind of thing quite often. The headlights are working fine, but the dashboard is completely dark—it's downright terrifying. Driving at night without dashboard lights, you can't even tell your speed, and before you know it, you might end up speeding or hitting something. It's extremely dangerous. Most likely, it's a blown fuse—that little thing protects the circuit by blowing first in case of overload. Otherwise, it could be the dashboard bulbs themselves that have failed, or maybe a loose wire connection. Older cars are more prone to this issue, as prolonged vibration or moisture getting into the wiring can cause the connections to oxidize. I once had to pull over on the highway, turn on the hazard lights, and dig through the manual to find the fuse box—just replacing a spare fuse fixed it. Remember, don't push through and keep driving; the risk is too high. Get it fixed ASAP. Regular checks on the lighting system can prevent this kind of trouble.
