    Hello all! New to the forum and have a quick question.

    I'm not the greatest when it comes to simple circuit layouts but here is my problem. I am setting up my wife's car to have daytime running LED's that turn off automatically when she turns on the headlights. These LEDs will be a totally different set of lights. I know that most DTL are a dimmer to the existing lights but we don't want that.

    The picture shows what I am trying to get at. I believe I might have the connections to the relay mixed up.
    Hope you all can help!

    Your second scheme will work except that the LED's will be glowing all the time the headlamps are off- like when you're parked and the engine is not running.

    Hello,

    SgtWookie is right.
    If there are modifications needed, let them be done by certified mechanic at the garage.
    This way you are sure the things are done safely.
