Wires Falling Off

During my attempts to get my clock hooked up and running I noticed two short wires with the male ends laying on the floor mats. The ends of the wires were corroded. I checked around some and found that they had broken off where they had been soldered onto the switches or bulbs. This is where age rears it's ugly head. Got them reattached. I can imagine that this could cause a lot of grief and pass unnoticed.
