    so i sign up so that i can learn more about circuitry. i dont know any of the technical terms so please bare with me while i might sound ignorant at some point.

    i really dont know where to start!! but this project is going on a car. I want a Led source to turn on when the ignition is off, but it is also wired to a timer so that it will shut off after a few minutes. That part ive perfected and have been working for years.

    every time i lock or unlock the car, the signal light would blink. here is the part i need help on, i want to splice onto that wire so that triggering the lock/unlock would trigger the led on. but at the same time i dont want the other power source to keep the signal light lit.

    The last few months i have been reading about forward direction diodes where it would allow power forward but not backward. so what kind of diode do i need. also do i need to wire it with something else or can i just add a diode into the splice wire?

    Here is a "illustration"

    Hi it's not allowed in this forum to discuss modifications on your car due to safety issues.

    Then you also said "i can learn more about circuitry. i dont know any of the technical terms" and " i really dont know where to start!! but this project is going on a car."

    One more reason they wouldn't allow a discussion.

    Sorry about that.

    You don't need to. If the discussion went further they close it.

    There was a link list of automotive forums somewhere here, can't remember where I've seen it.
