You'd be able to make some good money if you got around to making these. Jus sayin.

 

Im gonna try and look into it. It seems fairly simple. Im wrapping up a circuits and electronics class at georgia tech this next week so i have a decent grasp as to the basics.

 

Anyone happen to know the timing cycle of the turn signals? as in how long they remain on and how long off?

Finally got around to working on this and ive got a small scale partially setup
(2 leds so far and one delays, i have the chip for 3 leds just need to grab a few other parts and some more spare time)
I believe once i get the timing right i just need to swap the LEDs to some relays that go to the lights and it will work.
Only thing i havent figured out is how to actually make the thing. Right not its just wires and parts plugged into a breadboard

If i get some time soon ill make a short video or get some pictures at least.
If i can figure out a way to finish the product i might consider selling them for a much cheaper price then most AM kits

lastly if anyone has good pictures of their aftermarket kits and wouldnt mind posting them that would rock (not trying to steal ideas here, i already have my circuit planned out) just need to see some ideas for finalizing the circuit into a kit and quality comparison.
Aside from the $70ish i spent on the breadboard and wires for my circuits class i have only invested about $4 so far and i have almost everything i need for the small scale sequence for one side atleast

 

Not very long; fractions of a second really

I am actually building one for my Dad's old car but I'm using a microcontroller and LED driver to run 128 LED that can be sequenced in any pattern, we will be gutting the light and just reusing the lens on a custom shaped PCB.

There will be 8 columns of 16 LEDs with the ability to control each one individually, they are going in a heavily modified Delta 88 (600hp)

If it works I might make some for myself on my car.

 

When i was researching my possible design a few people recommended micro controllers as well but i have no knowledge of them at all. My electrical experience is limited to basic knowledge from my Circuits and Electronics class last semester and the Circuits lab im doing this semester. The 555 circuit seems to work just fine though. The only potential problem is the time it takes to discharge the capacitor. If i cycle it too quickly the second light will come on instantly. I dont think it will be a problem once i get the timing down since it will be on the same amount of time it is off roughly so it will have plenty of time to discharge.

 

I'm sure it'll work fine that way also, you could take a look at the arduino microcontrolers, they are cheap and real easy to program just as another option.

 

Just finished my small scale design using LEDs
All i need to do is change out the resistor/capacitor values to get the timing correct im just running low on supplies (lab is today hopefully i can "borrow" some more resistors)

I need to try and find the exact timing of the lights but im not sure the best way to do so, especially being away from my car.

Its not many parts involved too. The chip was $1.99 everything else i had already but its pretty cheap overall. As far as converting it from AA batteries and LEDs to the actually tail lights im still not certain but im making progress none the less

I have a pic and short video i just need to find the time to upload it. That is, if anyone is even interested.

 

Yeah, show us your progress.

 

im interested
