Need help with a flashing LED circuit
 
Hey guys, searching both the forums and online yielding no help. Either my mistake or design I cannot find the info I need.

I'm trying to design a circuit that will lite one row of LEDs when the running lights are on, yet lite up two additional rows of LEDs when the turn signal activates.

So.. 3 rows of LEDs total

Running lights - 1 row always on - never flashes.
Turn signal - 2 additional rows flash.

This is proving a pain because the front signals run off a dual voltage setup.

Any help would be appreciated, because I cannot find what I'm looking for. Thanks guys!

Can you measure the steady and flashing voltages?

Do you have spec sheets for the LED's you plan to use?

How many and what type of LED does each row contain?

I have the necessary voltages that the running lights and turn signals operate at.

I did some checking on my car, and I don't believe there is a way to separate the running light and turn signal current.

I will have to go through a programing software to enable the euro running lights so the corners only operate as turn signals. I'll just run a wire off my AE's for the running light portion.
