No more hitting the seat, boys, the LavNav is here.

You've felt it before-that wake-up punch to the shoulder when your early-rising housemate discovers the yellow treat you left on the rim of the toilet. "But it was dark!" you protest, only to be answered by another, more painful bruising blow. Enter the LavNav, a motion-sensing night light that clips to toilet seats to protect the innocent from the aimless and drunk. And for those who leave the seat up, fear not: LavNav glows red if the seat ajar, warning your dear flatmates and/or loved ones that danger lie ahead.
