Turn signal indicator light(s), Should arrows blink at the same time? Options

[theer]

Having had a few aircooled VW's back in the day, I was not surprised that my turn signal indictor lights blink as one. Then I read here that they are indeed supposed to blink separately (certain years, only? early vs late?)

Upon closer inspection, I see that the first blink is just the correct left or right arrow lighting up brightly, then after that both arrows blink, but only dimly... as in hard to see in the daylight.

Outside blinkers all work fine.

Any idea what is "supposed" to be happening?

My car is a mash-up of a '72 tub with interior, motor, etc. from a '70.

Thanks,
Tom

The circuitry driving the "K" lead on your flasher relay is weak. The "K" lead drives one side of the tachometer turnsignal indicators. When the "K" lead gives up, both indicators flash at the same time with 1/2 intensity.

You need a new flasher or rewire the tach turnsignal indicators to ignore the "K" lead.

You can make a jumper shown below to connect the indicators to ground instead of the "K" lead. I had the same issue with my flasher and just rewired the indicators as shown.
