Anyone else have bed-mechanism for rear shell light shutoff?

[RottieMom]

Does anyone else have a bed-mechanism for shutting off rear shell lights? I know a lot of folks have a button with their bathroom walls, but my TM definitely has some kind of mechanism tied in with the bed. I've been on a two week camping trip in Utah and when taking down TM in Moab I deliberately left light on over sink while I took down bathroom walls...light stayed on. But, after I unlatched bed and as soon as I started pulling it in, the light went out. I cannot figure out if there is some kind of contact or something under the bed shelf. If anyone else's TM is made like mine and you know where this mechanism is and how to access it, please let me know.

Thx,
