brake light relay question

[BranndonC]

how would i go about getting my brakes to go "Flash, flash, solid" when i hit the brakes, like 2 flashes with in a second or less, then stay solid from then on. I have led bulbs if that matters

Not quite sure I understand the point of the flashing, but I am pretty sure you'd need to build some sort of a little electronic controller...

Can you program PLC's? Know anyone who can? I do a little industrial control stuff, like relays and such and the only way I can see to do that is with a PLC. Plus, you'd have lots of adjustment.(you could scroll your lights around the truck or have them flash like a ambulance too.) Either that or you'd need two time delay relays, set at different times..... I'd say that would work too with a little head scratching

i dont know anything about electronics really, i know its somewhat possible though because my friend has 3 brake lights come on one after the other when he hits his brakes.

I'll do a little research and see if thats something I can set up using a 555 timer or something.

Gimme a day or two

Was thinking that's a timer deal too. Could possibly do it with an oscillator circuit, but I've not a clue how to go about that. Using a PLC would be like hitting a forming nail with a gold plated hammer. It'd work, but jeez....

 

[wildbilzrydn]

Yea, but just think about the possibilities, Infinite control, he could flash them 100 times, or have random or whatever. used PLCs can be had fairly cheap.....
Learning laddder logic wouldn't be bad either.

this is what i see when i look at that

But if thats what i need to do, maybe i could find someone who understands that to help me. thanks

cool, i'm on the right track now, i'm searching the net to find one for my application

 

[Russell]

I'm working on a custom chip for ya, to see if I can come up with something that is built to your specs.

Basically, I need to know exactly how you want the lights to behave, then I'll send you the diagram, along with a parts list. Pretty easy to follow the wiring, and easy to do too, you can get all the parts you need at Radio Shack (or is it called The Source by Circuit City down there too?)

the diodes going to the brake light would prevent any current from reaching the lights,
they are in backwards
