Key Light
Added light for the visually impaired. | |
Basic research (and common sense) reveals the visually impaired have problems where poor contrast and darkness are concerned. A small pocketable device that can house a key (in a similiar way a swiss knife houses a blade) also has an inbuilt light. When the key is flicked/pulled out, a simple connection
is made and the light (situated on the front of the the device) switches on. The key can then be operated one handed, and aids the use of a doorkey in poorly lit/darkened area's, without the need for additional lights. The added bulk of the product also aids grip and twisting of the key for elderly/disabled users. The device need only be plastic, and run on a small watch battery or similiar.
(??) Some alternatives.

This would also be useful for the alcohol impaired. |

why is grandma trying to get of the house with the torch? |

shh, we told her it was the key. |
|

If the key were made of a clear material, this effect could be (more or less) achieved. |

They do of course make conventional key covers that include a light, which is operated by squeezing it. |
|
| |
Of course, a key that lights itself up would be far better. There may be some problems with getting a material that will not snap off while in the keyhole, but metal isn't all that strong, so we should be able to come up with something. |
