Hi Tony.
thanks a lot.
you explanation is perfect. in fact i understood it the firs time.
i know a thing or two about diodes and resistors.
the problems are:
1. i have the same relay you mentioned but it doesn't work

maybe a bad one? i sent an email to V-LEDS support. lets see what they say.
2. in your setup, the lights will stay on, and just become brighter when turn signal is activated. using relay it will go on and off just like regular turn signal.
if i can get the relay to work, i do not need to run a wire to the car.
i can use the signal power to run the relay and the LED.
with that said, i love your setup. its great. much more simple to preform.
i never thought of dimming the running light using a resistor.
plus, look what i got in my office drawers:
