Came up with what I think would be a great idea, from the other guys post on putting LED's in the door handles. Once I get those in I would like to wire them to a source that comes on as soon as the door is open, goes off 5 seconds or so after the door is shut (if car is off) and stays on if car is on, the source, I found is the illumination ring aroung the key hole on the ignition, question is, what wire is that under the dash, does it supply negative or +12volts and do you think that would work?

By the way it is a 2004 Hyundai Sonata

im not shure of the colors or polarity(sorry), but testing would tell that. i do know however that it would absolutely work provided you diode isolate the circuit so that the leds you are wanting to put in the doors will not feed back into the ring. if the ring uses a negative trigger, tie into it and use a relay to convert the polarity and power the leds that way.

couldn't I just wire the led's to a constant hot and then run the grounds from the led and splice into the ground for this light?

you absolutly can, as long as the ring is triggered with a ground. but yea, that way you wont have to wire in a relay to convert the polarity. if it triggers with a hot you'll need a relay to convert to negative current for your leds.
