I am wanting to use a marine battery with a solar charger hooked to it to run some 12v lights in the chicken house so they might lay a little better. Is there a cheap timer out there that I could put between the the battery and the lights that would come on like at 4 or 5 in the morning then go off about 7:00 in the morning or am I just dreaming ?? Everything I am looking at goes from 120 to 12v. The few 12v to 12v timers I have found are expensive and if I do this I want to do it on the cheep. This is my first foray into something like this so if anybody has any better ideas please tell me. I just don't want to have to run a extension cord all the way down to the chicken house.
