Title: Weiser turning signal hyper flashing
Post by: scorpion32 on April 04, 2017, 01:57:15 PM
I just installed the Weiser extreme LED turning signals for my zero DSR 2016 model.
After the installation i noticed a significant hyper flashing on  each of the turning signals.

This is odd, since Weiser claims that their LED solution as an upgrade are especially designed that they are not going into hyperflashing.

Despite of this, there are usually two ways to get rid of this issue (as i learned from internet)
1. Install a resistor for each of the turning signals
2. Install a new load independent relay

Another odd thing is that they are not hyperflashing if i turn on "hazard warning flasher" mode.
Then all turning signals blinking like normal again. So the hyperflashing is only there if i use the turning signals as usual.

Can somebody of you explain this behaviour?

I would expect that they are also hyperflashing in "harzard warning mode". But they don´t.

Are there seperate circuit used for "hazard warning mode"?


Thx for helping me out of this.

the turn signal flasher relay looks at the current draw of each circuit. If its too low, it assumes one bulb has burned out and it flashes faster.

The LED lights use less power, so the relay sees them as burned out bulbs and flashes fast.. however when ALL of them are connected (the hazards) it sees enough load to flash normally.

There are 3 solutions:

1. add resistors to the lights. I dont like this as it wastes power, they get hot, and they're a pain to mount on a bike.
2. replace the flasher with a LED flasher. This works fine, except its expensive and its a parts store run.
3. modify your existing flasher into a LED flasher. This is what I always do.

LED flasher mod:
Just remove your flasher unit, then pop the board out of the plastic cube. its usually just two tabs.
There should be a 8 pin chip in there, just disconnect pin 7. I usually do this by using a utility knife on the underside and scraping off the board trace. takes 30seconds.
click it back together, plug it in the bike and you're done.
Heres a pic of the pin, from another forum.

edit: also attached a pic of what pins are what. your chip will have a notch and dot... the dot its at 1.. then 2,3,4 and straight across in a U shape.  You want to detach pin 7 from everything else.. either by pulling the pin, or scratching the trace.

Hi MrDude_1,

thx for the great description and the pics. Wow, the solution to modify the flasher is really cool and sounds easy to archieve.

Any drawbacks after the procedure? What is the functionality of Pin No 7?

It's the feedback for the light check.
Drawback, if a light is blown, it still flashes the same. .. exactly like an LED flasher as that's exactly what most of them are.
