What is the dome light on a car?

The dome light, also known as a courtesy light, is typically found on the roof inside a car. It illuminates the vehicle's interior, so you can see clearly when it's dark.

Why does my car dome light stay on?

If your dome light fails to turn off, it might be due to:

-A malfunctioning switch
-The light controls might have an 'always on' option
-The light's timer is broken
