Tell me where to buy / how to make a DC light timer

Our chickens [!] have trouble hopping up on their roost at dusk. We have glued a keychain LED to the inside of the coop and have been turning it on every night, and then off when they are roosting. I would like to have this turn on automatically at dusk and then off again an hour later. If this were AC I would buy a timer from the dollar store. For DC do I need to build something? [more inside]

How accurate is this dashboard light?

The "battery not charging" light on my dash went on; the mechanic told me I need a new alternator. Now the "battery not charging" light has turned itself off again. Does this mean my battery is, in fact, charging? [more inside]
