Lighted Door Handle
Install this lighted door handle and your roommate will know when the coast is clear, or when you're doing the bouncy bouncy with that babe from across the quad. The handle glows red or green, which you select using a small lever underneath.
Too bad it requires a power outlet to operate, and doesn't use a highly efficient combination of long-lasting batteries and low-voltage light. But this is no cheap thing, nor is it easy to install; its $440 price tag probably will confine its use to luxo-sport cribs or the bathroom just off the boss's corner office.
