Should Automatic Headlights Be Turned Off After Engine Shutdown?

[Henry]

Automatic headlights should be turned off after engine shutdown because once the engine is turned off, the alternator stops working, and the only power source for the entire vehicle is the battery. If the headlights remain on for an extended period, it can easily lead to battery drain, affect engine startup, and shorten the battery's lifespan. Automatic headlights can be turned off by quickly pressing the lock button twice. The activation of automatic headlights has a delay—the headlights will only turn on automatically within a few seconds after the light sensor detects dimming conditions. According to traffic regulations, headlights must be turned on in advance before entering a tunnel, so manual activation is still required when driving through tunnels.
