Abstract: A deadbolt having an integral light that is activated only when the deadbolt is properly locked includes a conventional deadbolt housing attached to a door. The housing includes a latch section that is mounted on an inner surface of a door having a drive member thereon. The drive member operates a latch shaft that extends and retracts a striker to lock and unlock the door. An LED is positioned on the latch section that is activated with an internally disposed magnetic reed switch. When the shaft is rotated to a locked position, a magnet positioned thereon substantially aligns with the magnetic reed switch to activate the LED. When the deadbolt is unlocked, the magnet is rotated out of alignment with the reed switch thereby deactivating the LED.
