How to Solve the Problem of the Reading Light Staying On?

Reading light staying on can be resolved by: 1. Pressing the car's brake pedal; 2. Pressing the car's one-touch start button; 3. The car's dashboard lights up, and the entire vehicle's power is connected; 4. Pressing the OFF button for the interior reading light. The steps to replace the reading light are: Slowly pry along the outermost edge with a flat-head screwdriver, avoiding the middle part of the light cover. Inside, there are small cross screws or clips; remove and replace them. The functions of the reading light are: 1. When the car door is opened, the dome light will turn on, and it will also stay on if the door is not closed properly; 2. When there is insufficient light inside the car, it provides enough brightness for passengers to read, without affecting the driver's normal driving.
The reading light keeps staying on, which I've encountered several times and it's quite annoying, mainly because it wastes electricity and damages the battery. First, check the light switch, usually located on the ceiling. Sometimes it might get stuck or dirty, causing continuous contact. Simply try flipping it by hand to see if it turns off. Next, check if the car door is properly closed. The dome light is designed to work in conjunction with the door; if the door isn't closed properly, it will stay on. So every time I notice the light is on, I first try closing the door again. If the door isn't the issue, the next step is to check the fuse. Locate the corresponding labeled fuse in the engine compartment or the fuse box under the steering wheel. If it's blown, replace it with a new one—this is something you can easily do yourself. If the light still stays on, it might be due to aging wiring or a relay problem. In that case, it's best to drive to a nearby repair shop immediately to avoid draining the battery and affecting the car's startup. During regular maintenance, pay attention to cleaning the switch and the gaps around the door frame to prevent dust buildup.
The roof light staying on requires troubleshooting from the electrical circuit level. I believe switch failure is the most common cause, such as worn button contacts getting stuck in the on position. You can manually remove the panel to inspect it, and apply some cleaner for lubrication and repair if necessary. Another possibility is door sensor issues - the light should turn off when doors are closed, but sensor misalignment or dirt blockage may cause malfunction. Clean or recalibrate the sensor with tools. A blown circuit fuse could also be the culprit; locate and replace it with the same model as specified in the manual. Deeper causes include wiring shorts or control module failure. For simple checks, use a multimeter to test if power supply remains continuous, but non-professionals should avoid tampering to prevent vehicle damage or personal injury. Continuous power drain is harmful as it quickly depletes battery voltage, affecting engine startup. Address the issue immediately by turning off the ignition when discovered. Develop the habit of confirming lights are off before locking the car to ensure safety and power conservation.
