Light for illuminating a keyhole

A light for illuminating a keyhole has a back plate 1 for attaching to a door, above the keyhole. A front casing 13 is securely fixed to the back plate by a push-fit arrangement, such that the casing is water resistant and prevents water from entering the interior of the casing. The casing 13 holds a printed circuit board 7 that supports a battery 5, a timer 9 and two bulbs 6. The light is switched on by pressing a button 12 located on the front of the main case 13. The timer allows the light to stay illuminated for one minute, before automatically switching the light off. The case 13 may be made from plastic, aluminium, or a combination of these two materials.
