The dome light switch controls the dome light. When you open and close your car doors, the lights turn on so you can see better. This is both convenient and much safer for you and your passengers. The courtesy light bulb switch works in a circuit, so when the circuit closes, the light bulb lights up. The switch is what allows you to close the courtesy light switch circuit.

The ceiling lamp does not burn for a long time, usually goes out after a minute or when you insert the key into the ignition. If you need the courtesy light to stay on longer, just press the switch and it will turn on again. If you forget to turn off the backlight, the battery will run out and your car may not start in the morning.

The fluorescent light switch can be turned off if you feel you don't need it. Sometimes they can be turned off by accident, so before you decide a light bulb or switch is broken, check to see if the courtesy light bulb switch has just been turned off. The switch should be in the "on" or "door" position so that it will light up when you need it. In addition, the switch may fail due to electrical problems. If you checked the switch and it is in one of the above positions and the bulb is OK, there may be an electrical problem with the switch. It is best to have a mechanic diagnose this problem so that the fluorescent light switch can be replaced immediately.

Signs that your light switch needs to be replaced include:

• Dome light flickers or does not turn on at all
• Backlight does not turn on even when settings are changed
• Light does not light up when doors are open

The courtesy light switch won't affect the operation of your car, but it could be a safety issue. This will help you get into the car and fasten your seat belt. Thus, you should be aware of the symptoms that your incandescent light switch is failing and check for the problem if necessary.
