Christmas Light Flashers

This is a simple cheap flasher circuit for whatever you want/need 2 alternating flashing lights.

I used a spare light controller and spare bulbs. You can get these items at walmart or anywhere else that sells stuff like this. I used a synchronized light set, and 2 40W light bulbs.

The connections were pretty simple. Just cut the wires between the control box and the connector and strip all three wires. Take your volt meter and set it to ac volts in the 120v range. BE CAREFUL HERE, I AM NOT RESPONSIBLE FOR PROPERTY DAMAGE, PERSONAL DAMAGE OR ANYTHING. Check to be sure that the 3 wires are not touching and plug the controller in. Take the 2 leads on your meter and check for voltage across 2 of the wires (I got about 30v ac) if you have voltage move one of the leads to the other wire and see if you still have voltage, if so the lead that did not move is your common and will go to both lights. If you did not get these results keep trying different combinations of wires till you get it correct.

Now you will take your common and run to both of the light bulbs on the large threads at the base of it. you can just tape it or if you want a more solid design but the lights in a base and just run your common to one of the wires on each base. Now take your 2 other wires and run to the connector on the very bottom of the light, 1 wire per light. Now you should be good to go...but just to clear it up a bit...heres a simple schematic.

Plug in the controller and test it all out.
