I just found this freebie and thought that others might like it too. I hate fumbling for my house lock when I am trying to find the keyhole in the dark. We do have a light that is supposed to come on when there is movement outside but sometimes my dear little boys turn it off. We don't use keys for our car thanks to the key less entry but hey there are still people that do.
Anyway, here is a link to a free key chain with a flashlight.
