Any chance of simplified wiring diagram, series V parallel?

You can draw it in your mind.

Series = Train cars

Parallel = Tuning fork

Or, you can go here: http://en.wikipedia.org/wiki/Series_and ... l_circuits

Does anyone done this before? I seem to remember something about LEDs requiring a resistor in the circuit..........

All advice at a level suitable for some one illiterate in the ways of electricity welcomed.

Warning light for what? I see no mention of the purpose of this light.

Duane - it blinks when the turn signal blinks.

An indicator light indicator light.

We're a bit slow in the country.

I used a 12 volt led with diodes to create this.

I no longer accidentally leave my indicators on!
I'll have to go and have a look at how I did it.
I told the guy in the electronics store what I wanted to do, he said do this, this, and this.
It worked




And a video

Head scratches............

From what I can see without digging too deep.

I ran one very thin power wire up one side of the screen to the led, and the ground down the other side.
I did it this way so as to have minimal wiring to hide under the screen trim.

I added a wire from each front indicator positive terminal and put a diode in each wire. Both of those wires were hooked to the + wire going up to the led.

The diodes prevent power going back down the 'other' indicator + wire. Left and right indicators would come on at the same time without the diodes.

The ground wire going down the other side of the screen goes to a ground terminal on the right indicator body.

I needed to cut a little notch in the top of the screen to 'receive' the led body.

Man, if I can do it...............

Here are the diodes and the led.

What sort are they?

Er, stripy blue ones and em.......a little clear led.

Just ask the electronics store guy, he'll know.

Jeff, I notice your usual indicator idiot lights aren't working. Is this due to you substituting the system, or were they already kaput?

No dis-connectors, but could be done easily.

The proper idiot light was not working at the time of the vid.
Sometimes it does, sometimes it doesn't.

Only one wire breakage in about 2 years? on the led from vibration of a soldered joint near the screen.
