LED turn signal hyper flash fix (1 Viewer)

[WristPin]

I installed some front LED turn/ park indicators. Naturally it flashed faster than it should. I did some research and found that if you remove ( or clip one leg) a resistor in the factory relay, it'll flash at normal speed.

I did this on my 86 4Runner and it worked.
Here are the pics:

How do you know which one to clip? or does it not matter?

Nice. I remember reading this tech article in my 4wdtoyota magazine but have since forgotten which resistor to cut. I just decided to ignore my hyper flash but I think now I’ll correct it. Appreciate the write up.

It's the one I zoomed in on. It has to be that one. Look at the pics u can figure it out. It's the only one right of the transistor.

No, I know which one in the pics. Just wanted to know why it was that one.

 

[WristPin]

Why? I have no idea. I haven't tried to figure out why. Who cares, it works.

Bottom line is … a more knowledgeable fella figured this out and shared it. Wish I knew about this trick before I bought a LED flasher for my truck and FJ40.

It has something to do with current running a different route through the flasher so you know you have a light out.
Cutting the resistor eliminates the "warning" circuit in the flasher. Or something to that effect.

I think this is a holdover from when flashers were bi-metalic strips that heated up when current passed thru. They heated up and bent opening the circuit. Then they cooled, closed up and made the circuit again. This also made the old school blinker sound under the dash. When a bulb burned out the current drops, the strip doesn't heat up as much and closes faster. Hyperflash. And it let you know a bulb burned out.

Generally speaking I just go to a led flasher so I can control the blinky speed to what I want.

Generally speaking I just buy the HD electronic flasher instead of the std bi-metal replacement flasher. Hyper-flash occurs because of how fast the bi-metal heats up due to the low "bulb" resistance. Electronic flasher doesn't care what the load is, it flashes the same. Sometime these are labeled as being for towing trailers.
