I would drop a video camera (phone camera, or other) into the trunk and close it. Does the light go out or not? It works like a refridgerator door, you open it and a light comes on -- close it and the light goes out. If the latch mechanism fails, then the light stays on and the battery drains out overnight...
I don't recommend it, but I have heard others use a small child (armed with a flashlight) for this task.
