Light ‘em Up Traditional Cache

This gadget cache is a lot of fun. One person can do it but teamwork is the best way. I put this here with the city’s permission. It takes a 9 volt battery which I have left for you in the eves of the closest little book library with a pink ribbon attached to it. It's there. You just have to put your hand up there and feel around.  Before you start give it a good once over to get your bearings. Here is your challenge. On one side is a row of screws on the other a bunch of holes. Inside some of those holes are lights. The screws on the one side will light up the lights on the other when you touch the battery to the right 2 screws. Each set of screws lights up a different color and number of lights. Look carefully in the holes. The combination to the lock is---blue---red---green---yellow. After you get the numbers right push the lock in and it will spring open. The bottom will open for you to sign the log and get a smiley. Have fun and Cache on!
