Gen 5 - Fix fast blink rate with LED Rear Signals

yes, just needs a resistor, I think 15K ohms usually fixes the problem, but it really depends on how many LEDs are in the fixture.

basically when and LED lights up, it offers next to no resistance (as opposed to an incandecant bulb which is just a resistor all the time) the "blink" circuit is basically a capacitor that charges and discharges to give you the blink... well when you introduce LED's in the circuit, they act as a short so the capacitor discharges faster then normal (fast blink)

if you want to, put a multi meter on the old fixture. what ever resistance is indicated is the resistor you need to add to the circuit for each fixture. Some US based companies are getting smart and adding resistors into the fixture from the start, but some "over seas" companies do not.

This. ^^^

oh, and the heat is not a problem, the blinkers don't operate but 5 minutes out of every hour of riding...

and remember the incandescent bulb produces heat as well (as much or more then the resistor would) and it is dissipated to the air.

I may be wrong on this but I believe that is backward. The LED has very high resistance and consequently low current draw, which causes the high blink rate. If you burn out a standard incandescent turn signal bulb (infinite resistance) the flash rate for the remaining bulb will be the same as with the LEDs installed..... fast.

well what LED's... actually all diodes have is a "gate voltage"... it takes a certain amount of voltage to open the gate... but once open, the diode will pass the amps with very little resistance

the reason it takes very little current to get a lot of light out of an LED is because the LED is actually designed to produce light (21st century tec) as opposed to an incandescent bulb which is a heater... that kinda sorta gives off light (20th century tec)

not sure about burning out a regular bulb, as you say, I remember the blink rate jumping (faster) to let you know you have a burned bulb and that i can not explain with the standard blink module of a capacitor and bi-metal strip.

You are correct, it is not a simple ohmic resistor like an incandescent bulb filament but is rather a voltage controlled device so a direct comparison to a resistor would not be accurate except for the effect it has on the entire circuit current flow.

I remember every time I've had a high turn signal flash rate with standard incandescent bulbs it always signaled to me that a bulb had burned out, thus high resistance (infinite) in one leg of a parallel circuit.

Looked at another way, you have two turn signal bulbs (front and rear) operating in parallel for each side, right and left. The total resistance for the front and rear pair is one half of each individual resistor value. If one burns out, the total network resistance is doubled and is triggering the high flash rate.

Just out of curiosity, do you know if the 15K Ohm resistor is installed in parallel or in series with the LED signal lamps to fix the high flash rate issue?

Thanks!

OK, here we go....lol!

LED Turn Signals Blinking Too Fast (Hyperflashing)

Is your LED bulb blinking too fast? No worries—it’s an easy fix! LED lighting draws much less power and lasts way longer than standard incandescent lighting that comes stock with most vehicles. Although the reduced draw of LEDs has advantages, replacement of turn signal bulbs with LEDS will cause what is called hyperflashing. Hyperflashing is when the turn signals blink faster than your stock incandescent bulbs did. This happens because your new LED bulbs draw such little power that your turn signal relay sees the bulbs as being out.

This is making my head hurt, you owe me a beer.....lol!

I looked up the load resistor on line and it is a heat sink type resistor designed to be installed in parallel with the LED. This increases the current draw to simulate that of an incandescent bulb.

Is there any reason why you can't use a universal variable resistor relay like the kind sold by TST?
Looking at the parts diagram on Bike Bandit it shares the same part number of multiple Kawasaki's... Looks like the only difference is mounting location of being under the tank rather than next to the battery like prior gens.

What brand of led? I have R&g aero led I'll get around to installing eventually. They installed them on a 16 zx10 on R&g YouTube with no issues but they do make resistors so idk

Not sure what brand these are. They came with the undertail eliminator from eBay.

Do you have a website link for that eliminator? Does it come with the license plate light and how much was it?

Thanks!
