Where is the trunk light switch of the Besturn B50?

The trunk light switch button of the Besturn B50 is located in the middle of the rear door. Trunk light switch: The trunk switch and trunk light are integrated. When the trunk is closed, the trunk light will automatically turn off. If the trunk light does not turn off, it indicates a malfunction in the trunk sensor switch. There is a locking slot on the trunk door; if the door does not engage with this mechanism when closed, the trunk light will remain on. Precautions for trunk usage: When going on a self-drive trip and carrying many items, pay attention to how the items are arranged. The principle of "large below, small above; heavy in front, light in back" means placing large objects at the bottom and small ones on top, while heavy items should be placed in the front and lighter ones at the back. This prevents rear items from damaging front items during sudden braking.
I've been driving the Besturn B50 for several years, and the trunk light switch is a bit hidden. Right in the center of the trunk lid where the latch is, when you open the trunk and look down at the latch area, there's a small black plastic button—that's the switch. When the trunk is closed, the latch presses against it, turning the light off; when the latch is released upon opening, the light automatically turns on. It's a pretty hassle-free design, no manual operation needed. Last time my light didn't work, I found that dirt and sand were stuck inside the switch. Cleaning the metal contacts with a toothbrush fixed it. When washing the car, remember to rinse around the latch area, as too much dust can cause poor contact. If the switch breaks, you'll need to replace the entire latch assembly. If you're handy, you can probably do it yourself in about half an hour, but it's still recommended to have a professional mechanic handle it for safety.
Previously, I helped a friend fix the trunk light issue on a Besturn B50. The light switch is actually integrated into the trunk lock mechanism. When you lift the trunk lid, locate the U-shaped metal latch hook in the center of the inner lid—the switch is mounted right next to it on a plastic base. The principle is simple: when closed, the latch hook presses down to activate the micro switch, turning off the light; when opened, the switch springs back, completing the circuit. This area is particularly prone to accumulating car wash residue or dust, which can cause the switch to oxidize and malfunction. I’ve handled several cases like this—simply removing the lock mechanism and spraying electrical contact cleaner on the terminals usually solves it. For a DIY check, you can repeatedly press the switch manually to simulate its action while observing if the trunk light flickers in response.
