Help, please! I'm kind of old to be just getting into the electronics hobby, but I've stepped into a project I just can't let go of! I want to add cornering lights to every vehicle in my garage, and I need help coming up with a workable driver or controller.
I know I'll need a relay for the light on each side of the car (2 relays), and each relay will need to be keyed by that side's turn signal. But how do I keep the relay pulled in with a "pulsing" signal? I've seen a circuit using a 555 IC timer, one using a 2N2222/2N3053 transistor, and one using nothing more than a 10,000 uF capacitor and a 1N4002 diode. I like the simplicity of the cap/diode circuit (the cap is wired in parallel with the relay coil, with +12vdc going through the diode, then through the anode of the cap). Anyone see a problem with such a circuit, or a way to improve without adding a mess of parts? Any/all input will be greatly appreciated. Thanks and God bless. - Chris
