Why do headlight stay on all the time on 2001 suburban
Headlights are not to stay on all the time,only front parking lights.
Headlights might stay on in a Honda Odyssey after the engine is turned off because of a courtesy timer. The headlights will stay on for a few seconds after exiting the vehicle so the driver can go into a building at night safely. If the headlights are staying on all the time, check the timer for this feature.
Did they used to go off with the ignition? On most cars, the headlights will come on at any time by just turning them on. The car does not need to be running or the key turned on.
This is an illegal modification.
Some vehicles have daytime running lights that are supposed to make the vehicle more visible to others.
There is a switch called the "twilight sentinel". That alllows you to adjust the time that the lights will stay on after you turn the engine off. Check to see if that is working properly.
Check all fuses and check for burn out headlights, high and low beams
Night time.
The correct grammar would be "Why would both of your headlights blow out at the same time".
Yes they should , they stay on all the time , while the ignition is on all the best Fester
All the time
Headlights should not be left on while the vehicle is not in use. If you are not driving, you will just drain your battery while having your headlights on.
