I am confused and need some help please.
What I am trying to do is make LED turn signal lights attached to my side view mirrors, WITH hazard signals.
I tap the signal from my car and have right/left blinking +12v wires. DONE! PROJECT FINISHED. Now, I tap the HAZARD SIGNAL which is just ONE WIRE that blinks. If I attach that wire to the leds, then nothing stops the electric from flowing back from left or right signal when THAT is powered on.
How do I isolate left, right signals from the hazard signal - which would trigger both left and right at the same time (without dropping the voltage which would dim the lights)?
