How to prevent the trunk light from staying on?

First, check if the trunk is fully closed. If not, simply reopen and close the trunk to resolve the issue. If the light remains on after the trunk is closed, it may be due to a faulty sensor switch. It is recommended to visit a professional repair shop for maintenance.
Sometimes I handle the trunk light issue myself to save power or prevent exposure. The direct method: open the trunk lid, locate the interior light source, usually a small bulb. Gently unplug the bulb connector with your fingers or a small tool—simple and safe, but remember to restore it afterward to avoid issues. For a more thorough solution, I remove the trunk liner, find the power wire, cut it, and insulate it with tape, permanently shutting it off. But be careful not to touch other wiring, as it might interfere with systems like the anti-theft. I recommend checking the owner’s manual for the fuse location; pulling the corresponding fuse is the easiest, taking just five minutes. A constantly lit light drains the battery quickly, risking a dead battery, especially in summer or during trips—regular maintenance can prevent this. If you're not handy, searching for model-specific tutorial videos online is also effective.
I always find it annoying and power-consuming when the trunk light stays on for no reason. A simple solution: use black tape or thick cloth to cover the bulb, which blocks the light immediately without damaging the car. Another trick is to check the trunk sensor or latch—if it's loose, it might falsely detect an open state. Inserting a piece of cardboard into the gap to make it tight can stop the light from staying on. From a power-saving perspective, the light being on all night might only consume 0.1% of the battery, but it adds up and harms battery life over time. Environmentally, reducing unnecessary energy consumption is more sustainable. I've also tried leaving the trunk slightly ajar after parking to avoid triggering the light or installing a small switch to control the circuit. Start with non-professional methods first, and if those don’t work, consult a shop.
