Default Turn signal indicator

Is there a way to wire up a single turn signal indicator rather than a left and a right?

Splice into both the left and right wires going to the front signals and run those wires to single indicator light.

There is a pilot terminal on most flashers for this. look for a 3-terminal flasher. Don't splice into both sides without a diode in each line or both sides will flash when either is activated.

Like this; but put diodes in the left and right wires, otherwise both fronts will flash.

I was worried it would backfeed. I didn't think about a three terminal flasher, good call!

6v cars are different from 12v cars - and the OP didn't specify.

Diode polarity - current flows when ANODE, the triangle, is closest to the positive. And the CATHODE, or bar, is closest to the negative.

As the indicator light is connected to earth ground the diode connected to said light is considered the same as the battery polarity post which connects to the car frame or engine. I.e. the diode anode connects to indicator light on 6v cars and the diode cathode connects to indicator light on 12v cars.

And if you get it wrong, no damage, it simply won't work. ADDED - the diodes themselves mostly have only the cathode marked on them, as a ring or bar nearest the cathode end.

But what I would do first is use a TEST LIGHT and learn if one terminal of the flasher will light when indicating right AND left direcction, in which case, problem solved without any diodes. Connect the indicator light to that terminal. It all depends upon the indicator circuit used, which does vary.

Typically the "pilot" terminal is marked with a "P"

Thanks for the reminder of the diode. Forgot and left that out of my answer.
