The trunk light cannot be manually turned off; closing the trunk light requires shutting the trunk. Here are the specific details about the trunk light: 1. Working Principle: The trunk light switch is integrated with the trunk switch, serving as a sensor device, typically located near the latch of the trunk door. When the door is closed, it triggers this sensor, causing the trunk light to turn off. 2. Fault Causes: If the trunk light remains on after closing the trunk door, it may be due to an abnormal sensor or poor contact, preventing the trunk light's sensor from being fully triggered when the door is closed.

As a veteran driver with ten years of experience, let me tell you whether the trunk light can be manually turned off depends on the car model. Most cars have a small switch next to the dome light—just press it to turn it off. However, some high-end models have automatic sensors that turn on when the tailgate is lifted and only turn off when the door is closed. Once, my friend's trunk light got stuck and drained the battery before anyone noticed. I recommend checking for a switch near the light or consulting the manual. If the light keeps staying on, the door lock sensor might be faulty.

Having disassembled over a dozen car trunk wirings, I can tell you: as long as there's a physical switch near the light, pressing it will turn it off. However, most OEM designs are automatically triggered—there's a door-controlled switch inside the tailgate that powers the light as soon as the door opens. To completely turn it off, you'll need to pull the bulb fuse, look for the 10A fuse labeled 'LUGGAGE' in the fuse box under the driver's seat. Rewiring is also an option, but you'd need to install a toggle switch in the switch circuit. It's recommended to have a professional handle this, as DIY wiring can easily cause a short circuit.

Last week, I finally figured out how to add a switch to my SUV's interior lights. The factory lights turn on as soon as the door opens, and there's no switch on the light housing. Later, I found LED trunk light modification kits on Taobao that come with their own switch and adjustable brightness. Installation was super simple: replace the original bulb with a magnetic LED strip and stick the controller on the side wall. Now, when I open the trunk, a light touch turns off the light, so camping gear retrieval doesn't attract mosquitoes anymore. The whole thing, including materials and installation, only cost 68 yuan.
