It is very possible for your car battery to die if you leave it on for 4 hours, but it’s difficult to give exact numbers on how long your car battery will last. Some people can leave their lights on for 4 hours and it won’t die, some people come back to a dead battery if they’ve left it for that long.

Hello there, a few different faults can cause the daytime running lights to stay on. The most likely would be the headlight switch, DRL relay, or a wiring issue. Running lights work, brake lights do not. It sounds like you may have a bad brake light switch.

1. You left your headlights on. Many newer vehicles have headlights designed to turn off after a certain amount of time. But if your car doesn’t have this feature, your headlights may stay on until you either turn them off or till your car battery is completely drained.

Sensors rely on ambient light level rather than on vision and visibility as you see them, so they won’t always get it right. Heavy rain or fog in daytime can reduce your vision and vehicle visibility to dangerous levels, but it might still be bright enough to prevent automated lights from coming on.

IntelliBeam is a General Motors lighting technology that automatically turns the vehicle’s high-beam headlamps on and off according to surrounding traffic conditions.

Once you’ve enabled IntelliBeam and the low beam headlamps are on, a Green “A” icon will display on your instrument panel. The feature will then turn the high beams on and off depending on vehicle speed, lighting conditions and other vehicles it detects.

When driving at night, the auto high-beam system can automatically turn on the high beams when its windshield-mounted camera detects no vehicles ahead, and return to the low beams when vehicles ahead are detected – a great convenience.
