sequential turn signals

LP1____________Filament Lamp 12 or 24V

I found this schematic on the net.  I was going to use it, but it just flashes each lamp once.  I went as far as to go buy the parts to do it with and then realized it wouldn't work the way I want it to.  Would it work if I used cascading caps?

I was thinking of using the turn signal wire to start the chain.

 The transistors might not be able to handle the current requirements of some filament lamps used in automotive applications..

 Some thoughts.. depending on how your tail-lights are set up, stepping on the brake might have your brake lights sequencing.. is this something you want also?.. You can use the third brakelight to stop the brake lights from sequencing when you're stepping on the brakes.

 There are better circuits out there.. look into semiconductor circuits, not R/C.

Hey,

Can you design a circuit for me that sequences the three lamps for signals.  Don't worry about the brakes, I'll figure that one out.  I would like for it to use redily available parts, say from Radio Sux, Srr shack.  I don't care if it uses a 555 or any combination of the 55? series.

Thank you for all the help and posts earlier.  And thanks in advance for the help now.

BTW, why would you use a timing IC when the caps do all the timing?  I'm new to electronics, I wire houses and buildings for a living, but have never really messed with electronics.

Thanks again.

This is not limited to extems only.  Anyone feel free to chime in.  I just copied and pasted from a PM I tried to send him and he had too many.  Thanks all.

ohh sorry I missed this, forgot to delete some of them PMs

He says to look at semiconductor circuits because for repetitive flashing it will be much more reliable, and the time constants will be kind of large...

I dont really have the time to design anything currently, but if I was going to design this with all discrete components I would probably go with a 555 driving a johnson (decade) type counter (like a 4017) , and some output transistors, probably mosfets to directly wire the lights to. I will try to get some time to design something. Although if I had my way it would be microprocessor based
