I have a question for the electrical-minded.
I have a leaky circuit in my new LED signal/tail/brake setup in the rear.
Namely, a small amount of current is leaking back when you signal one way, and dimply illuminating the opposing signal as well. No its not a bad ground, yes we tested it, no there is not a crossed wire and yes we tried resistors and/or an LED flasher
I spoke to a couple electrical guys today. I was told to put a diode in series before each light, on +. Recommended was IN5400, 401 or 402.
Also, I asked about making a more obvious difference between tail/brake illumination. To that I was told to either a) wire a resistor in parallel on brake circuit (will increase brightness) or b), more desirable, wire in a resistor in series on the taillight circuit (will dim light). Recommended was 330ohm/36ma, adding one at a time, up to say three, to get look I am happy with.
Here in lies my final dilemna.
I don't believe I will need the resistor in the signal circuit in the rear, because we tried it with and also without. BUT - it wires in parallel between both + on both signals.
IF I do decide to use the resistor, do I still put the diodes in the circiut, in series each signal line +, BELOW the resistor? I am concerned that current above the diodes will still bridge across that parallel circuit, and cannot limit that travel with a one way diode.
