Cor blimey, list, there must be as many ways to wire turn signal
indicators as there are automotive engineers. "Now, connect a wire from
the X terminal to your right earlobe, and screw a christmas tree bulb in
your belly button..." Presto! Next year you can lead Santa's sleigh
through the fog...
But I Flemming Larsen's approach is seriously cool and may try it. A
common gripe about the bugeye is that the turn signal indicator is
brilliant, and annoying. Except mine, which won't light even though I
could not possibly have made a mistake in wiring ;-). I have not bothered
tracing where the signal goes awry (probably a bad ground--it always is),
because I was not sure I wanted this thing dazzling me at night. However,
I also worried about forgetting to cancel the signal, and being run down
by a truck as a consequence. So I betook myself to Radio Shack, and
bought a 12 volt solid state buzzer, which I mounted under the hood
(bonnet), connected between the indicator outlet and ground. When the
signals are blinking, this thing makes a sound like a canary (budgie)
being seriously mistreated just within earshot. It's annoying, to be
sure, but it does not mess up my night vision, and it is impossible to
forget to cancel the signal. You cannot *wait* to cancel it.
I am tempted, tho, to connect the original indicator as F. L. suggested.
The additional resistance offered by the nonblinking bulbs should dim the
indicator nicely.
Or maybe I could rig up a circuit on the headlight switch to drop the
voltage to the indicator when the headlights are on...
The Flemming Larsen method:
> Now, connect a small indicator lamp between the wire from the switch's
> right turn contact and the wire from the switch's left turn contact.
>
> When a voltage is present at the ungrounded end of the right turn signals,
> current will flow through the indicator lamp, through the left turn
> signals to ground. The current through this circuit is not high enough
> to light the bulbs in the left turn signals, but is high enough to light
> the indicator lamp on the dash.
