4 light chaser

I hope that I can explain this clearly. We are a Mardi Gras parading group in the New Orleans area, dunebuggies to be exact. FOr years we have had 2 55watt lights on top our roll bar that flashed back and forward with a common wig wag flasher. Now we have changed the lights to leds and they work great. We would now like to add 2 additional lights on top for a total of 4 lights, each with 2 leds in them, but we would like to go to a "4 light chaser system" without breaking the bank. Can anyone help\ john

If you mean 1 2 3 4 1 2 3 4, then I suggest a 4017 decade counter. You can make the 4017 into a "divide by 4" counter by connecting the 5th output to the rest pin. The 4017 is a 14-pin chip (IC - integrated circuit) but soldering and output buffers (transistors of MOSFETs) are required.... Let me know if interested....

VERY INTERESTED BUT AT SAME TIME VERY LOST 1 2 3 4, 1 2 3 4 is ok, but would it be harder to do a 1 2 3 4, 4 3 2 1 ? and what will I need to put this together? many thanks

How much current does each LED draw?Kevin Pierson

Kevin,

I cannot find the draw listed on the site, but here is the link if you dont mind taking a look,  I am thinking on putting a total of 3 of these in each light, for a total of 12 of these on the total run of 4 lights.

Wow, twice lost! You can do 12344321 by connecting whatever order you want to the sequenced output. IE to the 4017s outputs 0,1,2,3,....7,8,9 you connect lights 1,2,3,4,3,2,1,2, etc or 1,2,3,4,4,3,2,1,1, etc. This is done through diodes so that one 4017 output does not power another. The output after the last in the sequence is connected to the reset pin. You can cascade multiple 4017s to could above 10.    And I think you skip the first output (usually denoted as "0" though sometimes as "1") - I'll have to check. You'll also need a clock (pulse) source for the timing. It's the chip and soldering of the links - and the diodes - and output drivers (probably 4 MOSFETs and 4 resistors). Plus the timer (a 555 chip with a few components else some other oscillator). But if you want something with more complex outputs, you are better off with a programmable sequencer.

I think you all are reading a bit more into my post. I should have been more clearly.

I have NO idea of what you are talking about. I was expecting that maybe I could hook up some wig wag flashers in a series, as far as building something,

I have not done that since the Boy Scouts, some 45 years ago.

WHere do I buy something like I need.

Is anyone serious about trying at least to help me with this or are you all just a bunch of nerds getting your kicks?

Depending on how much current you'll need I can maybe help. I can provide you with a small circuit that is time adjustable with (4) 600mA outputs. The circuit would be on a production quality circuit board centered around a 1.2mghz custom programmed processor. The module would have a knob protruding the through the top to adjust speed and would connect to your vehicle through a genuine Molex wiring harness. I could even set it up to do 1-2-3-4 1-2-3-4 or 1-2-3-4-3-2 1-2-3-4-3-2Kevin Pierson
