I am making police style flashers for the inside of my truck (don’t worry I am allowed to have these lights on my car. For those who are not allowed by law be just for you know you can be charged with a felony if you are caught with them).
They are going to go on the side back windows. Each window will have a box attached to the glass. In each box there will be 6 LEDs (3 red, 3 amber) so that is a total of 12 LEDs.
I want it to flash in a “wig wag” style. That is where all Red Leds come on then off. While the red is off the Amber Leds come on then off and then repeat. The flash speed should be about 90+ flashes a min.
What I want is a control box that will hold the circuit that I will mount under the dash. I will run the power and ground cable to each box on the windows.
Now I want to run off the power of my car. I know that it is normally 12V but not sure of the current. And don’t want a spike to kill the leds or if the volts go down to cause the LEds not to work.
I was looking at using a 556 timer. Is this the best. I need it to be simple to make and the cheaper the better.

Look at products SL905RCE and SL905ACE
If anyone is up for drawing the circuit that would be a great help. I’ve been having trouble with it. Any questions just e-mail me and post here. firstname.lastname@example.org. If you have aim catch me on that Firedog18.
