I'm trying to build my own alternating flasher circuit to drive 2-6 LED light boards. The LED boards are premade and consist of 22 LED lights each, I've placed a link to a picture of the lights at the bottom of the post. The lights I have come with a control box that only offers 2 flash modes.
Here's some background. We had an issue with a set of lights in a cruiser, only the blue would work and not the red. I took the red apart and discovered it to be cold joints on the led board, tapped them all with my 30 watt and fixed the problem right up. While I had the light apart I noticed a circuit board with a 12F629 chip. The set from the cruiser has 19 different flashing patterns. The power is controlled by an on/off rocker switch and the pattern is controlled by a momentary rocker switch, each press of the momentary changes the pattern.
I'd like to build something like this myself. I'm currently researching PIC programming to write my own code for the chip or perhaps use their code in my build if permissible. I've tried searching around for something like this but I haven't had much luck. Most of what I find consists of the 555 timer chip which won't serve my needs. I want to be able to have full control over the different patterns and use all 19 patterns in my design. By using a programmable pic I can alter the patterns at any time.

J5 and J6 on the board connect to the LED light bars (6 LEDs on each, 2 bars). I can post pics of the actual led bars if needed. They are small bars, approx 3" x 1".
The large black wires come from the control box.
If any more information is needed I would be glad to post it.
If I can get this going I've got a few different project ideas in mind.
After reading several posts here I also want to mention that I am a LEO and will be using this setup in my personal vehicle so there are no legalities for me to contend with.
