LED Indicator Lights With OEM Flasher? (UPDATE)
 
My flasher for led is adjustable no resistors needed just a tweaker for the led warning light ,hardly any power drain nice and bright

I use All-Round banding to make P-clips to mount mine - Not sure how long velcro will hold up....

Velcro is surprisingly tenacious when vibration is present, especially in a shear force. It also acts as a vibration isolator. I use it extensively in Radio Control aircraft powered by single cylinder 4-stroke engines up to 30cc that develop over 3 HP. Lots of vibration and frequent negative G maneuvers. The weight of a plastic flasher unit will be light duty for Velcro.
The engine in the video below develops 3.4 HP @ just over 8000 RPM. It is quite a shaker.

That flasher I ordered is adjustable for flash rate.

Your bike - not going to tell you otherwise - have at it.

Mine is LED rated and adjustable too - Adjusted it the full range, and could not get them to flash correctly, ended up using resistors. Have had to do this with 2 bikes.

Again - just reporting my findings.

FWIW
 
My CNW flashers use normal bulbs, but flashed fast with a standard thermal relay. I just used a load sensitive electronic flasher and it worked great. Nothing to set. Available at the local auto parts store.

Appreciate all of the suggestions. If my $12 Kawasaki flasher doesn't work satisfactorily I'll have lots of options.
 
UPDATE

A few things that were needing attention;

Although the Amazon flasher was adjustable for flash rate, it seemed to be very voltage dependent. The flasher would not work unless voltage was > 13.6v. I just didn't feel comfortable with this. I switched the Amazon flasher for the Goff's LED flasher and the Goff's flasher will work at lower voltage, not requiring output from a charger/alternator.

With the low current requirements of the LED flashers, there was feedback through the single warning light causing all 4 indicators to flash at once, I installed the Goff's LED INDICATOR WARNING LIGHT TWEAKER

Now the turn indicators work independently as they should.

True, but adding resistors negates the power saving feature.

Are you sure?

The circuit with the higher resistance will allow less charge to flow, meaning the circuit with higher resistance has less current flowing through it. This brings us back to Georg Ohm.

So the way it works as I understand it...the flasher unit old type bi-metallic strips heat up, change shape/length, which opens the circuit contact point, shutting off the lamp(s), strip cools off, regains its previous low temp shape/makes contact once again, closing the circuit, starting the heat up etc etc etc. With an LED in circuit instead of incandescent lamp, less current flows through the flasher, insufficient to make enough heat so no flashing happens, just constant on. adding a resistor means more current passes through the circuit to ground, so the flasher behaves like it used to and gets hot enough to open and flash the LED.

If you use the original flasher unit to maintain the same frequency it needs the same current going through the unit, therfore the
total resistance has to be the same, it can be solved with additional resistors in parallel to the LED, but in this case it needs exactly the same current as with normal bulbs.
In other words LED with the original Flasher unit is not a good solution.

Not a good solution? Why not? Same load as the original incandescents would provide.
