Default Flickering turn signals

Recently there was a thread on the problem of LED turn signals flickering. Here is a solution that I just came across on the internet. I haven't had the problem but for those of you that do, here is the info.

LED Turn Signal Resistor Kit
When you replace the dull turn signal bulbs with more modern LEDs, most vehicles will start to hyperblink due to the LED bulb using less power. In this situation, your vehicle may think that the bulb is out. Eliminate this hyperblinking issue by ordering this LED Turn Signal Resistor Kit from CJ Pony Parts.

I hope this helps.

These resistors are sold by most vendors to provide a sufficient load to operate the original thermal flasher. I think the flickering described in the earlier post you mention was caused by EMI from ignition wiring.

Not necessarily. I don't think we decided that the EMI was truly the problem in that thread, just that it might be the problem. These are different value resistors than the ones for gauges or coils. I don't know if they all would work in all situations but I know the 100k resistor that I use when putting a 2+ volt LED in a Model A tail light housing keeps it from blowing out by lowering the input voltage and it also smooths out surges when the LED goes on. My electronics GURU told me to do it that way, it is not something I figured out on my own.
Here is the difference in the specs on a Runtz resistor for gauges and the CJ Pony resistor for LED signal lights. They are different, it may be important but it may not:

CJ Pony resistor for LED turn signals:
Resistance Rating of 6 ohm, 50w


Resistor for gauges:
"Runtz" transistorized 12v to 6v reducers allow you to use your original 6 volt electronic devices (like gauges) on a vehicle that has been converted to 12 volts. You will need a "Runtz" for each 6 volt electric gauge on your car.
Designed for 12 volt negative ground systems only. Screw type terminals. 1.5 ohm resistance, 4 amp max load, 25 watts.

Sorry, was looking at some bad info.

The Runtz is simply a different resistance. The voltage drop across any resistor is dependent on the current through it. You may or may not see 6V out of it.

Add one of these resistors to each side to make a thermal flasher work with LEDs:

An electronic flasher doesn't need the extra load resistor.
