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.

What would be very nice would be if the
full outside perimeter edge of the key
were (also) able to light up brightly.
This would have the effect of not only
looking quite nifty at night, but also it
would aid recognition of which key is
which, to a significant extent (especially
by comparison with each other) |
|

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. |
