How to turn off light in front trunk?

[rubberduckie]

Sorry for so many posts, but it has been a bad week for the Boxster. When I was at my mechanic's yesterday having a new battery put in, they told me to keep a towel under the front hood if i wasn't going to drive the car for a while so that the front hood wouldn't lock again if the battery died (grrr). So, i went out to do that today (once again the car won't start.. see other post) but i noticed that when i open it up a light comes on. this is only going to kill the battery even faster so i looked around for the pressure button that the trun would hit to turn it off when it was closed, but i couldn't find it. I really don't want to be locked out of the trunk again if the battery dies so if anyone knows how to turn this light off i would really appreciate it.
